Lapdock/Webtop Resources/Q&A - Motorola Droid RAZR

Here are some links to all things Webtop. Also a place for general discussion on getting the most out of the Lapdock and/or webtop environment. I will update this thread over the next 1-2 ds. Feel free to add links or tips.
Lapdock:
Purchase options:
Razr native: Lapdock 100 (10", $199) or 500(14") (coming soon)
Bionic Lapdock(11")($199) (same as Atrix lapdock but with ports in proper orientation.)
Atrix Lapdock(11"): Requires modifaction of ports (flipping ports and shave away some excess soft plastic.) No headphone port access.
-AT&T: OOS, All4Cellular($64 refurb) also OOS
Atrix Modification instructions:
http://forum.xda-developers.com/showthread.php?t=1374743&page=2
Bionic thread but good pictures. You will need to shave away extra plastic on the edges and back of the cradle for the Razr to seat properly to avaoid disconnections.
The other option is to run extensions from the ports or to thread the ports behind the cradle.
Linux Mod (Eternity Project):

Props to kholk. Please support his efforts. Turns lapdock into a fully functioning linux laptop while maintaining access to phone/android features on lapdock.
Webtop on a TV options:
1. HD Dock ($99)
2. Travel adapter ($29): http://www.motorola.com/Consumers/U...rs-and-Adapters/Motorola-Travel-Adapter-US-EN

http://forum.xda-developers.com/showthread.php?t=1372246
Please support work by Fenny. 400757 is also working on it. Still needs touchpad/keyboard functionality, so currently works only with a bluetooth mouse/keyboard.

Known lapdock issues/limitations:
Atrix lapdock:
No headphone jack access
Concerns of security of phone (either standing upright or connected to exposed ports)
Screen does not open past about 120 degrees (flaw in original design corrected in lapdock 100.)
No HDMI out
HDMI Webtop Mod:
No phone as track-pad or keyboard functionality yet
questions about lagging
Webtop environment
Slow performance on webtop native apps (Firefox) as compared to android native apps. Especially regarding choppy video through firefox.
No native RDP solution (can use android RDP apps on full screen.)
No way to install additional linux apps (addressed by Eternity Project's Linux mod.)

I should correct your statement about the ATRIX LapDock.
There are two ways to access the 3.5mm jack of the RAZR while docked into the ATRIX LapDock:
1. Drill two holes into the lapdock's dock, it should be large enough for a 3.5mm jack to get into it with its cable, then connect the 3.5mm jack to the RAZR and make it to sit in the dock
2. Drill two precise holes into the lapdock's dock, buy a 3.5mm female and a 3.5mm male connector, make the male connector to fit locked into the hole near the USB connector, make the female connector to fit locked on the side of the lapdock's dock. Solder the wires so that the male connector is connected to the female connector.
The first way isn't so clean, but the second way can get you into troubles as the work has to be done with maximum precision, otherwise, you could result with two useless holes on your lapdock's device dock.
As for the HDMI out on the ATRIX LapDock, we can do something for this thing to be possible. As I don't know how the Lapdock 100 HDMI OUT works, the only thing that comes to my mind right now is:
Required:
1. HDMI connector (the same on the phone, can't remember if it's female or male, but it should be female)
2. Some wires
3. A switch
You should drill another two damn holes into your Swiss Che.....emh, LapDock dock, and fit the HDMI connector into it.
Then, you should fit into the first hole the HDMI connector and into the second one the switch.
Now, you can solder the switch between the dock's HDMI connector and the external one you've put into the hole.
Use the switch to select which HDMI connector to use when docked: if you use HDMI1 you'll view all on the LapDock display, HDMI2 for TV/external HDMI display.
As you can see, the HDMI MOD is difficult to realize, but when you've got some experience and knowledge... you can do everything you want with your devices.

This is very good, but im unsure about it being in the development area.

Hah, I 100% agree, and did not mean to post it here. I wanted it to be in the general thread (or maybe it belongs in accessories), but after I accidentally put it here there was no way to move it using thread tools. It would be great if a moderator could move it.
I thought about copying and pasting into a new topic in the general thread, but it did not seem worth the effort.

I was thinking about doing a headphone mod to the lapdock, and then realized the simplest work-around is to use a bluetooth headphone.

I’m new in this forum, but when I buy my Motorola Razr XT910 its comes with the motorola travel adapter for webtop .
I don’t understand why in other countries sales the phone without this adapter!
PD: Sorry for my bad English but I’m new in this to wrote in this language

I am considering getting the ATRIX web dock and ir remote. Will the remote work with the Razor? And does the razor have the same web dock media centre looking software the ATRIX has in web dock mode controlled by remote. Thanks

I searched but could not find anything on how to get terminal access on the Razr. I found these instructions for the Atrix.
http://forum.xda-developers.com/showthread.php?t=981658
But this does not seem to work for me.

Is that related to my post? Thanks

Sorry, it was late when i wrote that. I meant terminal access to the webtop. If you follow the link I posted it's referring to that.

So in relation to using a media centre looking software like the one on the atrix via the ir remote how would this be done.?

Also does anyone know anything about webtop2sd? I'm pretty new to all this and I was looking through the post but I haven't quite figured out its purpose? I mean apart from transferring the webtop to the sd card.

I know one thing I'd love to know is if there is some kind of repository or archive for the webtop image files. The only one I know of is the one included in the razor utility 1.4. I'm not even sure what version it is yet.
I can't find any other ones and I'm trying to see if downdrading my web top version (current 2.0.139) would fix the evbridge loop (causes excess CPU usage) that shows up when web top is loaded with the HDMI hack.

Could you do me a favour?
Run these two commands from your phone then paste me the result:
ls -l /etc/localtime /usr/local/bin/evbridge
cat /etc/osh*
I'm closely pinpointing the evbridge issue.

HD Media Dock for the attrix for $30
Micro USB extension from usbfirewire for ~ $12
Already had a Mico HDMI Cable.
Remove Dock top plate, connect micro usb extension from dock to razr.
Connect Micro HDMI from RAZR to TV(one in dock is just a pass though)
$42. A lot cheaper than the HD Station ($99). Works Great.
Tested with USB Keyboard/Mouse/Card Reader/Thumb drive/ Logitech C910 Webcam. All work great on the RAZR.

What a coincidence. I had no idea that you replied to this thread. You got mail sorry i didn't see you online on chat earlier.
It appears that changing the timezone settings to manual, changing the timezone setting that was selected by the automatic settings to anything else and then rebooting fixes the evbridge loop issue. It must be kept on manual, but you can change the timezone back to what it was before (in my case EST GMT -5). It then continues to work without the evbridge issue.
This is tentative though I haven't hooked up a display to see if the trackpad comes up but I will be doing so very soon.
Edit: the trackpad does not come up but the evbridge issue does not show up when in webtop mode. I am using it right now . Performance is much better in webtop
Edit 10:22: Don't how or why but the trackpad is working now just plugged it in to do stuff and it came up with the track pad and it works. cpu usage is still normal.

It's nice, but looks too big for listening on headphones while traveling.
now that is what you call multitasking!!!
wow thats what i need!
Again it depends on whether using the headphone adapter stops the handset microphone working. It's the one bug in the Martin Fields adapter.
Has someone tested it and can tell whether it is strong and reliable?
usb adapter
I got mine 2 weeks ago, it sits in the car and does a great job. it IS well made and not cheap plastic. now if ony i can plug a usb stick/hdd into it

Yes I'm looking for an adaptor so I can plug in a normal memory stick (using the usb host function) can anyone let me know where I can get one of these (UK ideally).
usb host -- external harddisk
The 3 in 1 adapter is one thing...
The message about enabling HTC to be USB Host ... is another.
Where did you find the needed drivers / s/w for HTC to be able to connect to a usb mem stick. (Or external HDD, or my Creative Zen Vision:M)

i belive that we are limited to the hardaware....otherwise we could use the files from the UNI.
To those of you who have purchased this 3 in 1 adaptor:
Does the end which plugs into the Hermes have exactly the same shape as the port on the bottom of the Hermes (with all sides of the port at right angles except for one diagonal notch in the lower right hand corner), or is it a standard mini-USB plug with notches on either side of the plug?
The reason I ask is that I would like to be able to plug the HTC-designed cradle I bought from Expansys into a desktop speaker system, but the HTC cradle only has the standard shaped mini-USB ports.
Interestingly, the HTC cradle has two mini-USB jacks, one marked with the USB icon (for synchronizing), and one marked with a power plug icon (for charging). I wish it had a headphone jack too.
Why does HTC make it so hard to use this device to listen to music? How about an honest to goodness 3.5 mm headphone jack on the bloody device itself? How about not making us choose whether to charge the unit OR listen to music? I hope they don't wonder why the iPod is so successful, or why so many folks are interested in the iPhone...
Okay, rant over. Any ideas or pictures of the device side of the 3 in 1 adaptor (you could use the Hermes' built in 2.0 mega pixel camera!) from those of you who purchased it?
the hermes does not support USB hosting... just passthrough... therefore will not work...

I was wondering the same thing. This would solve a huge problem that I am having with my setup as well.

I presume this means that you would not be able to plug in something like a USB memory stick with some sort of USB Mini adaptor ?
Just thinking outside the box, not even sure what I would use it for if it was possible.
Mmm .... I guess transferring files to TyTN when there is no USB cable or WiFi available.
Guess what I really need to do is to get as USB adaptor for the Memory Card ...
Right Angle or regular mini USB
Just wondering if anyone who has bought this knows if this is a right angle or a regular mini USB on the end that plugs into the phone.
I have one of these. Its brilliant, well... to an extent.
It has the same non-standard usb shape as the HTC plug that goes into the Hermes. It has to, to connect to Charging, USB and audio.
I use normal headphones with it, works a treat.
I also have a car mount, and my little project was to use my 2.5" Wifi all-in-one disc/access point in the car (Its a Asus something or other). Use WiFi on the Hermes to connect to 80G 2.5" disc in the car boot, and play music using cassette adapter through the car stereo.
Only problem is, if I mod my car mount so this adapter is in it permanently (which I have done), audio from the phone is always diverted through the adapter, whether you have phones plugged in or not.
Which means I wouldnt hear TomTom directions unless I was using the Phone for audio (i.e. not use car radio or CD).
I have this splitter as well. I ride a motorcycle and this thing is great: it allows me to listen to music and use spoken instructions from TomTom for navigation at the same time.
However, I do have a small question. I'd like to have an 'activation button' and a noise cancelling microphone in the helmet. Anyone know if there's a headset around that offers this, one where I could just cut off the earphones??
By the way, has anyone tried hooking up both regular headphones and a complete headset? Does the TyTN/splitter allow audio to both at the same time?
OK, I just got my new adaptor (Stereo Headphone Adapter For ExtUSB 11 pin to 3.5mm) and I was thinking that I can't really charge the phone while using it. This dongle might be the solution. Has anyone tried it with this:

Why wouldn't you be able to charge the phone while using it? Bluetooth earpiece, regular headset, etc. all work fine while charging. Unless you mean 'on the road' when there's no wall outlet

[MOD] TVOut - beta 001 - 3-1-2011

Updating with just the patched classes, instead of the update.zip due to complaints. Inside you will find the source to the app (yeah doing it in Settings.apk would be better, I'm being lazy) and the modified classes for services.jar. This is not working yet, it is being uploaded so other devs can tinker as well. We need kernel source before this will work, more than likely.
Issues known:
->breaks dock support.

Cable Details:
GizmoDroid said:
From what I have gathered, there are three common types of cables most people might have hiding in their closet. There are multiple devices that use these types of cables, but most of them tend to follow those pinouts. If we definitively find out the right layout, you can mod a cable you already have, or get them for dirt cheap off of ebay/monoprice (fully recommended, they have nice cables for cheap).

A) Samsung Galaxy S official cable, Nokia (cable #CA-75U), cables that come with most Media Players (Archos, Gigabeat, Creative, Zen Vision, Cowon iAudio, Apple iBook)
B) Standard Camcorder cable -This is the most likely kind that you'd find at a store if it doesn't specify what it is for.
C) Zune
D) iPod Video
[Size=+0]Quick Fix[/size]
Some cables you already have can be used without modding the cable, even if the pinout isn't the same.
Type B/C/D device with a different Type B/C/D cable
By plugging the video plug into one of the audio channels, and vice versa, you can swap the signal without cutting your cable. Refer to the chart to see which audio channel to plug the video into.
Type B device with a Type A cable
Plug the cable in all the way, then pull it out one notch. You will have only one working audio channel though, so this will sacrifice audio quality.
[Size=+0]What type do I have?[/Size]
If you have a multimeter, it is easy to find which type of cable you have. Set your multimeter to resistance (ohms). Put one lead on an RCA signal pin, then touch the other to each of the 4 spots on 3.5mm jack. Whichever one shows ~0 ohms means that that RCA signal is connected to that spot on the jack. Some MM have a continuity mode that will beep whenever you make a closed circuit. This is easier since you don't have to look at the MM while you are doing this.

Our tests were inconclusive, as we only had one cable of an unknown pinout and one tester. We have gotten rid of all errors, the device sees the cable now, runs the service and communicates with the service.
Patch is for Superclean based on eb01 with voodoo. I am not responsible for any thing that happens due to this patch. Please don't apply unless you know what you are doing and can recover a "soft brick" on your own.

What the!!!??
Have you actually gotten to see anything on the screen yet?? I'm going to bust this out and try it now. I have my own cable that has been sitting in the packaging for weeks just waiting for someone to come out with this. I will test it out and report back shortly. I have no qualms about bringing my Fascinate back from the dead if I bork it ...
If this works, and something actually shows up on the TV, super big thanks!
Wait as in a micro usb to composite/component? HDMI?
Wait, wha? This would be awesome!
Before I blow $40 on cable ... do you know if this is supposed to only work for analog NTSC output or if HDMI output over the microUSB is one of the available options?
edit: sorry finakechi, you beat me to it.
Subscribed.
3.5mm to RCA, we haven't gotten output to the screen. I ordered a grip of cables and a fascinate, but it wont be til friday when I can test it.
Testing shows it seems to work, and nolonger errors. We just haven't gotten output. I posted here with hopes of someone having a working cable with the right pinout, or another dev picking up interest and joining us.
the usb to hdmi cable is to costly and I won't be looking into it unless someone sends me one. I think RCA is good enough.
I know we have two cables at work that are from two different digital cameras..they both work with their respective cameras but only one works with the fascinate and the vibrant phones we have here... the pinout looks the same though... so you may be getting output and you just don't know it yet.
Got an error report:
<fuzzhead> i do think your app/patch is kind of working or trying to work though. i opened gallery and video player and both fc'ed while i was playing with rcas. leads me to believe it was trying to output
If someone with experience using logcat can reproduce this, and get me the log it would greatly help.

If the cable doesnt work, switch out the wires, it might not be yellow that is video out. Also if it doesnt work, then we just investigate further.

Hahaha. That is a little bit of an "oopsie."
Edit: Well, this is weird. I installed the patch, and now it's doing the robotic female voice and taking forever to reboot. I wiped caches and such, but I don't remember changing any voodoo settings ... hmm. Yeah, it's still talking to me. Weird. We'll see what happens. I'm on EB01, but not a superclean. Suppose locking up a phone is as good a reason as any to try a new ROM.
Well, after a successful boot, the app indeed runs and lets me change settings without any apparent issues - no force closes, etc. I have the mini jack to the three RCA breakout cables. It's the Dynex brand from Best Buy (purchased when I still had employee discount, of course!) With TV Out enabled or disabled (I tested PAL and NTSC both just for fun) I couldn't get the TV to display any audio or video regardless of how I plugged each cable in - red, white, or yellow. I am going to have to find some cable clamps and do some individual circuit testing and see if it's send out any signal at all, and trace it. It should at least be sending out some kind of audio, because I tested regular stereo headphones, and they still work. I'm excited to monkey around with this a bit. If I can narrow down which signal is going where on the 3.5 to RCA adapter cable I have, I can at least detect, hopefully, that audio is still being sent properly, and even more hopefully, if there is a pos/neg combo that will magically be a video signal. No more time to work on this tonight though.
Thankyou, jcase. I am waited for it, will beta test it as soon as get my cable.

Not all cables will have the correct pinout (which we dont know what it is).

[DIY] "Car Dock" Cable - USB audio out + charging - UPDATED! (11-9-11)

I just made my own "car dock" cable based on the information over the "Fun with resistors" thread.
Basically I have a cable with a micro-usb connector that switch my phone to "car dock" mode, audio via usb/aux and charging.
CHECK THE 2ND POST FOR UPDATES, PICTURES AND A QUICK VIDEO.​
WARNING:
This cable can physically damage/destroy your phone if made incorrectly.
If you don't have experience soldering electronics and small parts maybe you should not try this.
The usb cable will NOT work for sync/data - just charging.
I'm not responsible if you damage or destroy your phone/property and/or injury yourself or others.
Use this instructions at your own risk.
​Parts that I used:
micro usb male connector (Digi-Key pn: 609-4051-ND)
619K ohm resistor (Digi-Key pn: RNF14FTD619KCT-ND)
6ft 3.5mm Stereo Plug/Plug M/M Cable (MonoPrice.com pid: 644)
1.5ft USB 2.0 A Male to Micro 5pin Male 28/28AWG Cable (MonoPrice.com pid: 5137)
I should have used a longer cable but that's what I had at home
This is the pin-out for the usb connector:

Preparations:
1) Cut one of the aux cable connectors and expose the 3 wires:
Yellow = common ground
White = right channel
Red = left channel
The left/right channel may be inverted, test on your phone before you make the cable.
2) Cut the micro usb connector from the usb cable and expose the 4 wires:
Red = +5vcc
Black = ground
Green = not used
White = not used
Soldering:
Start with the audio cable:
Solder left channel wire to pin 2
Solder right channel wire to pin 3
Do NOT solder the ground wire yet
Now with the usb cable:
Solder red wire wire to pin 1
Do NOT solder the ground (black wire) yet
With the resistor:
Solder 1 resistor leg to pin 4
Solder the other resistor leg + audio ground (yellow wire) + usb ground (black wire) to pin 5
Almost done...
Test all the connections for short-circuit with a digital multimeter
Triple check for the right cable on the right place, you don't want to put that +5vcc on the wrong pin, it will fry your phone!
Just finish it with some epoxy glue to make sure the cables won't break where you soldered them and some shrink tube for a polished finish.
You must go to Settings > Dock Settings > Audio output mode and enable it to have the audio-out working.
I will post pictures next week when I will make a new cable with longer usb and better finish.
The cable I have now works fine, it's just ugly...
I hope this info will be useful for someone
Thanks to TheBeano for the info about the resistors

Hello all!
Thank you to all the people who rated this thread and enjoyed the info
After building my first cable from two different cables and finishing it up with some epoxy putty I started searching for a better and easier way to build this cable.
While searching on some Chinese accessories website I've found an iPhone USB/aux cable that would make this build easier and nicer.
This is the USB/aux cable from DealExtreme.com (item #34654):
From eBay I got this micro-usb connector with a "housing" (link):
The resistor is the same from the original post:
With this parts in hand I started by taking the iPhone connector apart:
With the soldering iron I removed the connector and with an blade I removed the cable "terminator"(?) so I could expose more wire and use my own "terminator"(?):
Using a multimeter and my "pro-mod" I was able to verify the cables and plugs.
All cables matched so I started soldering:
After checking for short-circuits and fixing the mistake I always make (I invert left and right channels) it was time to squeeze everything inside that tiny housing:
It looks nice but now let's test it:
Pictures are worth 1,000 words but a video is priceless (don't mind the music):
Great write up!

Nice write up. Very useful. Thanks
Awesome, gunna order some of these parts.
Exactly What I Wanted
This is EXACTLY what I was looking for!! Once I see a picture/video of it in action, I'll get the parts. Question is, are you going to make your own car dock for it? Or are you going to purchase a generic dock? I'd like something that I can slide the phone into easily (and have the phone be horizontal). I am curious about the possibility of getting Digital Audio out instead of Analog. You seem to be the expert, do you think that's possible? Thanks!
I'm 95% certain digital audio out is not possible, except maybe for MHL/HDMI audio output via the MHL adapter.
There just aren't any provisions for it.
Thanks guys for the replies!
I got some PM about selling the cable. Right now I can't do it as I don't have enough time to make a good and durable cable.
The cable I have is kinda put together with epoxy putty and some shrink tubes.
Today I tested the cable and it works fine on my car.
I just found some iPod/iPhone cable that I think can make this build be easier and faster, basically you will change the apple connector for the micro-usb and add the resistor. I still waiting for the parts to arrive to test this new idea.
As Entropy512 said digital audio isn't possible with this setup but I will look in to it in the future to see if it's possible to use the mhl adaptor just for the audio.
Tomorrow I will post the pictures and a small video from it working with my current cable.
Thanks once again for the replies!
This is awesome thanks!! If you can create a few of these I would definitely be in for buying one. I am hoping to replace my itouch in the car with the phone. I already have a nice dock thus just need a cable.

So digital audio out is not possible (that's kinda what I figured). But what about getting a USB->Digital Audio Out? I realize the kernel would have to support a device like this. I'm very new to the Android scene (less than a week). But I'd think that it would be possible. I can't post links yet, but it was a $25 USB->SPDIF device on Amazon. The reason I'm asking is that I'd like a way to eliminate the "road noise" (alternator noise) from my music.
And how are you controlling your music in your car? Do you have a remote for the phone? Bluetooth? Or are you doing it the "old fashioned way". LoL! Thanks again for your efforts!

You can use MHL->HDMI adapter then put in a HDMI->Digital audio converter to get the digital audio out without any modification to software. MonoPrice.com has both but I believe the later requires some external AC power.
I have an official Samsung car dock for my Captivate. After reading OP's post, I decided to mod that car dock. I stripe out the part that connects to Captivate USB port and contains microUSB socket for power and 3.5mm audio jack (it already has the required resisitor inside). Now all I need is some 5-wire microUSB male to female extension cable. This kind of cable is hard to come by but do exist.
I did some reading in the 'fun with resistors' thread, and while this mod looks to work, I'm worried about the lack of sufficient charging amperage. It seems that in order to do "high current charging" you need to short pins 4 and 5 on the micro USB plug. Well, those are in use by the audio output. This seems to be a _major_ design flaw in MHL. So basically, you'd have to turn off anything you don't need (WiFi primarily, maybe Bluetooth if you don't want integrated hands-free with your car's head-unit) in order to get an actual charge. So maybe this cable with a Tasker function to turn off those services and activate your Car Home app.
Please take what I say with a grain of salt. Again, I'm very new to Android and I'm probably wrong.

The device assumes that a proper high-current supply is present when a dock or MHL ID resistor is detected.

In theory, I believe the device has USB Host/USB OTG support - but I know very little about enabling it. It MIGHT be possible to get USB sound cart to sort-of work - but getting the phone to route audio to the "new" interface would be extremely difficult.
I used to deal with Digikey decades ago .....
Are they selling "onesies" of parts now or do you have to buy multiples?
The items that I've listed you can buy just 1.
They have other items where the minimum order is 5000.

Mouser is usually a bit better about minimum order quantity though - I think digikey improved over the years in that regard.
Usually Mouser has their quantity price breaks earlier.

Question about the dongle (not "when will i get it, how do i get it, etc.")

So, i've seen a few pics of the dongle both assembled and disassembled... my question: if i disassemble my dongle and plug it into my dock can i use it? Physically it looks like it would fit, im just wondering if it will function... any ideas?
Edit:
To avoid confusion, i want to go [Prime] -> [Dock] -> [GPS]
The dock has both a male AND female connection.
Aparently it does not function as of yet, might be software? What pins are being used on the gps and what pins get passed through on the dock? If were lucky its just a software thing, or maybe it requires some pins to get passed to the dock connector.
We had the first person who opened up said it didn't work when he plugged it into the dock. The pin layout might be different or could be a software thing. If a software issues, developers here should be able to modify the file path or whatever that the GPS software in prime looks at. Instead of looking for dongle at the prime 40pin connector, maybe it could be rerouted to the dock 40pin connector. Or software change that'll detect either and link it up accordingly.
Plug it in to your keyboard dock you mean?
>i disassemble my dongle and plug it into my dock can i use it?
Mating connectors use the male-female concept. Tablet plugs into dock, so one is male, the other is female. Dongle plugs into tab, so it is opposite gender of tab, and same gender as dock. Ergo, dongle can't plug into dock, coz like-gendered connectors can't mate.
---------- Post added at 02:22 AM ---------- Previous post was at 02:09 AM ----------
BTW, for those who want to mod toys at the chip level, might as well get well acquainted with your soldering iron. Little bitties in dongle means SMT fun. Contrary to popular belief, you can do SMT stuff w/o fancy tools. A vid primer, then:

But doesn't the dock also have another 40pin female connector on the side of it? This is how it gets charged with the prime power adapter that has 40pin male adapter on the end. Plus someone who opened it up already said they plugged it into the dock but it wouldn't work.
I know what you saying about like gender adapters not being able to mate but I believe the dock has a male adapter, to go into the prime for dock connection, and another female adapter on it so it can be charged at the same time.
demandarin is correct, the dock does in fact have both a male connection to connect to the prime and a female connection which the power adapter connects to.
Guess i would have to look into if the dock passes through all the pins or just a select few, however data at least should work, i connect my computer to my prime through the dock all the time to transfer files (instead of undocking the prime and connecting that way)
Edited the first post to include information thus far.
>But doesn't the dock also have another 40pin female connector on the side of it? This is how it gets charged with the prime power adapter that has 40pin male adapter on the end.
If the port is only used for charging, there'd be no data lines going to it. There's no reason to daisy-chain the charging connector to the docking connector. If you want to do that, then you'd have to figure out the pin-out. Even then, the odds of something going poof is still pretty good. This ventures into the territory of "if you have to ask, then the answer is no." It's not a good idea.
If you want working GPS and working dock at same time, ditch the dongle and go with active GPS antenna mod for the built-in GPS. It's simpler and more straightforward. If you're good, you may be able to have an inset port for the MCX connector and have nothing sticking out. Not sure if there's enough space to do that, though, so you may have a slight nub sticking out.
Also, the fact that you can't turn off the dongle is another issue with a Daisy chain solution

Are you talking about the beer can mod with wire or did I miss a thread along the way.
>Are you talking about the beer can mod with wire or did I miss a thread along the way.
I'm talking about an aftermarket GPS antenna like these below. You'll need to mount a SMA or preferably a smaller MCX port, then jerry-rig some power for the "active" antenna (because GPS signal is weak, it needs an amp to compensate for signal loss, which needs power). Come to think of it, since cable length isn't excessive, you can try a passive ant and see what happens. The key is to get the antenna element outside of the metal case, and replacing the crappy internal PFA one. The connector is intended for quick-on/off use.

No but the 40 pin on the dock may well just be used for charging .. data may be connected to the SD/USB sub board

MHL to HDMI adapter

I haven't seen anyone post about the MHL capabilities of the DNA yet so I figured I'd try my adapter from my Nexus... it works fine with the cheap 5 to 10 dollar ones you can buy on amazon... you just need to be sure that you power the adapter it wont work without external power

I also have a mhl adapter from pny but I did not connect power to the adapter and the external display worked. Was your display on the phone and tv laggy or smooth after you connected the adapter? Were your videos in sync with the image produced on the phone itself?
MHL adapter kit
The MHL adapter for HTC DNA from iBOLT features a 2 meter (6ft) extension cable so you can stand in front of the TV and play Angry Bird, racing or whatever other games you prefer. With licensed MHL technology it is a real 30 frames per second so there's no delay and the sound quality is great when playing even advanced games. My kids love MHL, they only want to watch Netflix kids programs now without painful commercial interruptions.
The only thing to be aware of with Android MHL is that some sites block the HDMI port out. Two examples are Hulu+ and HBO (they don't block it from iOS). Most others, like Netflix and almost all web streaming sites works perfect. Google Play has an amazing picture quality on the newer videos when you rent them, absolutely clear 1080p resolution if you have enough WiFi bandwidth. The best use of MHL is to show photos and videos though on the big screen TV. The quality with good adapter is near perfect and the phone is charging while you are doing it too.
The "cyber Monday" price for an iBOLT complete MHL adapter kit with 6ft HDMI cable and the required 1 amp microUSB wall charger is only $24.95. Feel free to ask any questions and I'll check back daily here. Here's a YouTube video showing the technology and the kit I was referring to. The Samsung OEM has a very good reputation if you don't like this... https://www.youtube.com/watch?v=QmaKIJ90Xz4&feature=plcp
The image and everything was in sync... Sounds were good I watched a little but of transformers... The picture looked like crap but that is because it's compressed over Google play... You tube looked great

I bought one and it works well, but the framerate seems a little slower. It is usable, but certain apps seem to not allow being shown via the HDMI such as NFL Mobile and Hulu Plus.
The Samsung adapter for GSIII works on the DNA.
I have experienced issues with hardware accelerated subtitles using the MHL cable. Viki shows video but no words and that is kind of useless for me. Fortunately downloaded subtitles play in MXplayer with the software subtitle option.

I think I know the answer to this question but I will ask anyway...lol
Is there any MHL to HDMI adapter cables that do NOT need an external power source for the adapter? Seems kinda crappy to have to plug power into the adapter,
If so, a link to one would be greatly appreciated
Just put my order in to upgrade from my Thunderbolt to the DNA. Figure I will want to get a wireless charging pad, the MHL to HDMI adapter, and a micro USB to USB to mount external storgae.
As an aside...I cannot believe no company has actually created a micro USB to Micro SD adpater cable! I saw some links to threads here where people actually built their own...pretty cool...but hard to believe no company has stepped up for this. With the form factor fo phones moving more towards the DNA, One X, etc, I would think those would sell like hotckaes!
While browsing this thread I came to wonder about the DNA's mirroring. So when the right cable is connected, mirroring becomes available? Makes me wonder if a cable exists that might be micros USB on one side and (don't laugh) RCA on the other. My car's head unit had an add-on that allows RCA video inputs to display on the nav screen. It worked back when I used an iPad occassionally.
