Has anyone here tried hardwiring a power supply to their car dock?
I'm planning on tackling the project in the next few weeks and I can post any relevant pics/info, although the wire routing and dash removal would be different depending on the vehicle. I can at least provide some info on parts and a good way to tie in the charger to the vehicle's wiring.
Anyone who has tried this before is welcome to throw in ideas/tips.
I've done this with every phone I've ever owned, it's no big deal really.
You going to run it on aux power? Or something always on?
I'd seen a tutorial online on another (inferior) android forum that showed a car charger tied in through the dashboard power outlet's wiring.
I used a fuse tap & simply wired it into one of the fuse blocks in my Ford Escape. The power from that runs my phone charger & an HDMI scaler.
I have a 7" dbl DIN DVD/NAV screen in the dash, & I use an MHL adaptor to hook up HDMI video out to that & two other monitor screens in the rear.
I rip DVD movies to my 32 gig card & play them on that setup. I also use SlingMobile to play live TV on those screens while traveling. My wife watched 4 hours of HBO on demand movies while we where traveling recently.
The HDMI also runs music from my card/Pandora/iheart radio/Netflix & Sirius Radio online to the truck system.
To me, this stuff is no big deal but I was an auto mechanic in my younger days & also sold/installed competition grade car stereo setups.

Good stuff. Are you using a cigarette lighter/aux adapter and just bringing it out or did you find a way to hard wire the micro USB cable directly?

Ok, my real question was how did you back it down to .7 amps or whatever the dock charger is? I just phrased it horribly lol

It tools some doing, but I finally got this working perfectly and figured it might help someone out.
I have a 7" DVD/NAV screen built into the dash of my truck. I have always been able to display my Slingbox, Netflix, ripped DVD movies etc from my phone to that screen using HDMI out from the phone to an HDMI SCALER as my truck stereo doesn't have HDMI in and this gives composite connections.
This worked great with my DroidX and Droid Charge, but my new Rezound does not have dedicated HDMI OUT (boo) so I needed an MHL>HDMI ADAPTOR.
the first adaptor I got from htcpedia (htc M490) was defective. When I plugged it into the phone (and the USB power cord) it showed the HD out in the task bar, but nothing showed on the screen and in 30 seconds the adaptor quit completely.
At that point, I ordered the HTC AC M500 12 pin adaptor and that works super. It has both HDMI out and analog audio. I plug the HDMI cord into the scaler for video and a headphone cord hooked into the aux in on my killer truck stereo for sound. The sound is better that way than coming through HDMI.
This setup works AMAZING. I can run anything except the NFL APP to the 7" screen with killer sound.
Don't knock the new port too much, the functionality is awesome.
Here is a link to what all it can do.
I'm not knocking it at all, at first I was because it seemed no matter what I tried I couldn't get it to work.
I had a brand new AC M490 MHL adaptor (the one other posters where recommending), with a brand new very high quality HDMI cable and could not get it to work at all which was extremely frustrating. This was annoying especially in light of the fact that my previous three phones worked perfectly in this setup (although the DroidX did not do HDMI mirroring which was really annoying at times)
Now, with the AC M500 MHL adaptor (which seems more compatible in every way) it works better than any previous setup I had and does it all with just one-plug at the phone end.
The 500 uses the exact same plugs for both the phone and the USB power cable as the original Rezound AC charging cable instead of the looser fitting mini USB like the DroidX. Either will work I guess, but one is a loose sloppy fit and the other is a nice snug fit like the OM charging cable.
The 500 also has both an HDMI out and an analog audio out as opposed to the 490 which only gives you the HDMI. I have found this to be an advantage soundwise. I noticed this with both my DroidX and later with my Droid Charge.
I noticed that running both the video and sound through the HDMI cable from the phone produces a noticeably weaker sound than running just the video through HDMI and then the audio out from the headphone jack (or the analog audio out on the adaptor in this case) This gives a much fuller sound with more bass etc. For some reason (I'm not sure why really)
This worked in all my previous setups and continues to hold true with the Rezound.

Interesting, actually cheaper on Amazon than on ebay!
HTC MHL AC M500 12 pin adapter
I recently got interested in this and bought one from Rakuten, but the audio doesn't work. I tried headset, earbuds, powered speakers. Is the audio port just a 3.5" plug? Maybe I got a bad one. Video works OK though.
I'm also curious that mine says, "9VDC 1.6A" on the back, but our phone chargers are 5V. Sure wouldn't want to burn up my phone. Anybody else's say 9V on the back of it? It doesn't say input or output or max input or anything, just that voltage designation.
I bought a Fosmon HDMI cable from Amazon and it never worked with the tablet (ICS .14/5v). No sound, no video with 3 different TV Sets (Sony, Samsung and Sanyo)
Which brands does indeed work in your experience?
Brand will make absolutely no difference in terms of whether the cable should work or not. It's either a bad cable (better brands will be less likely to be bad, but even the highest end brand gets an occasional bad cable) or a problem with your prime. Theoretically it could be a problem with the display but since you tried with 3 different ones that's HIGHLY unlikely. Every micro HDMI cable no matter the manufacturer will be the same not counting production/QC problems.
In terms of brands that more likely will have lower failure rates, just pulling up the amazon list of micro HDMI cables available here are a few that I recognize:
Belkin
HTC
Monster
PNY
Rocketfish
Samsung
Tripp Lite
Yeah you'll probably pay more than $3 for the cables they sell, and the next $3 Fosmon is probably at worst only 25% more likely to be bad than one of them, so you can roll the dice and try with another Fosmon or try a more established brand and hope with your odds better you don't get unlucky again.
Monoprice cables work just fine. I have my entire home theater and all my families setups running off of them. Had at least 20 of their cables and never a bad one. I use this one for my prime:

what are you using hdmi for?
Just curious, what is the (your) purpose of using the hdmi out? I don't see a lot of usage for it, but perhaps I am missing something?

Watching movies on a big screen, playing games on a big screen, giving presentations on a big screen.
Imagine your prime as a portable game console or movie player you can plug into any hotel TV. And of course it's just like using a laptop to project a presentation at a business meeting. Yeah you can watch movies and play games on the prime itself but it's nice to be able to throw it up on the 50 inch TV, sit on the couch and play a racing game or whatever.
Monoprice is one of the cheaper cable providers but I have also had fairly good luck with them. I do AV installations as my business and I've used hundreds of them for low cost jobs where I have to hit very aggressive budgets and have had failures but only maybe 10% or so (which is still crazy high for the industry average) and in fairness to them they replace them quickly and without fuss. Digital cables don't have any quality issues beyond the signal gets through reliably or not; once the signal gets through you can literally use a wire hanger bent straight and get the same exact quality as a $5000 monster cable. So I'd feel safe using a Monoprice cable for a digital signal (HDMI, digital coax, optical) but I would recommend not using them for analog signals (RCA, speaker wire, etc). Also since often shipping is more than the cable itself (this micro HDMI cable is actually pretty expensive compared to their normal prices) I normally get a few of whatever I'm ordering to make sure a single bad cable doesn't hold me up.

At my college they only have VGA on the projectors unless we hang from the ceilings, is it better to get the micro HDMI to VGA or just get the micro to full HDMI and just use adapters to get to VGA?

My overall dream and desire
= Have a tablet WITH GPS, with a nice screen, that I can buy cheap that supports at least Honey Comb. I want it to look good in my car and do things for the car. Slacker radio/google music/GPS duties. It'd be cool to have it doing email, etc.. but not needed.
I own a samsung epic. I had it almost completely figured out and installed....but then we find out that if you place your phone in desk dock or car dock, it farks up the sound output and aside from physically modding the dock with new parts there's no way to fix it.
ENTER THE FLYER!! WOOHOO!! Solution is found! HTC FLYER + MHL adapter and I'm all set!
Beautiful screen, MHL adapter means only one wire is seen etc etc etc.
What's the problem?
The DAMN CHARGING SYSTEM. I've got a 2 amp car charger that EVERY android device sees as "AC" ...
HOWEVER when you plug in this 2 amp AC charger into the MHL adapter.... DUN DUN DUN, the Flyer only sees it as a USB CHARGER, thus meaning that if you're using the thing to play music and having the screen stay on (as I do) the tablet cannot charge faster then it drains!!! WTF.
So the solution now is that I have to have two wires sticking out at opposite ends and I wasted 30 bucks on a damn MHL adapter.
Why the FARK can't companies get their SH!T together and just make something that works. IF you're going to be charging through the MHL ADAPTER WHY ON EARTH would it limit you to the lower charge rate...say you have it plugged into the real AC adapter...I'd assume this means that while going through the MHL adapter IT STILL would show up as USB charging (again not enough to keep up!!)..
Farking Stupid companies drive me insane.
here's someone complaining about the same thing on a samsung... http://www.droidforums.net/forum/galaxy-nexus-accessories/196278-mhl-adapter-charging-issues.html
so farking stupid.
Because...............the designers never farkin believed anyone would frickin try to mount a frakin tablet permanently in a frickin car. And frickin for sure never thought anyone would farkin use the MHL in a frickin car. LOL

haha, FINE.
However, if you take this tablet INSIDE and say you want to watch a netflix movie on your tv.
You do this
Oem charger >> MHL ADAPTER >> FLYER
So you're watching a netflix movie via hdmi with all your OEM branded stuff.
Guess what........it STILL doesn't charge fast enough. Will you make it through a 2 hour movie? Maybe... what if it's a 3 hour movie? Probably not.
How stupid does it get.
Here's the car charger I'm using.
http://www.amazon.com/Motorola-Vehi...Q9CA/ref=sr_1_1?ie=UTF8&qid=1333722016&sr=8-1
What I really would like is a tablet OR PHONE
that has this:
- Horizontal docking option (like the evo 3d)
- Dock MUST include AUDIO out
- Dock must be able to charge at the AC rate, not the USB rate
- Real GPS inside
- Wifi
- Preferably be no less than a 4 inch screen
- When routing Audio through dock it must not be degraded to changed in ANY form (aka samsung epic dock)
That's all I ask for. is it really that hard to find this elusive product??
I don't know of any devices that have a dock that meets your needs. There are of course many devices that meet your needs minus the dock. Or you could buy a Ford car with Sync and sync your device to their system.

Um... OR we could use the PS3, the PC, or any of a million other devices to watch netflix instead of our tablet..
I mean really.. do you have ANY idea how easy it has been made to connect almost any computer in the world to a TV and stream netflix? I mean really it is ONE cable. In addition to that.. I can't even begin to name all the devices that people can use to stream netflix.. but, let me just give you a few.
1. TVs with it built in.
2. PS3
3. Xbox 360
4. Wii
5. netbooks
Before you go off about how "stupid" it is.. you should really ask yourself how many people are relying on a tablet as their all in one go to device for everything.. I would say those people are stupid.. The HTC flyer was never in a million years designed to be your all in one go to media device. it is a great device designed for casual use.

Ok so we are now designing "multimedia tablets" to do less and less?
Your argument is pretty dumb mang.
Just because I have a full HTPC at my house doesn't mean that HTC should design a tablet, give it an HDMI out and then make it impossible to charge it (powering the device while losing battery charge is not "charging" while you're using it to do what they designed it to do.
i currently have a transformer prime and also have an aaxa p1 jr pica projector coming in the mail im hoping to set up something called the sixth sense device but im hoping to find a way to plug the projector into the transformer prime and im having a hell of a time trying to find a cable that will connect the 2
I picked up a converter from tiger direct.
Search for Sabrent HDMI to composite RCA/s-video. I've used it to watch movies on older TV's while traveling and it works great. the one downside I would say is that it requires power. But I believe thats the only option no matter which brand you go with.
I also picked up an RCA RF modulator to convert that to coax for real old equipment. it all works as expected.
thats what i didnt want to hear lolz i was hoping for something that didnt require additional power to make it mobile and like always i bought it before making sure it will work so i will need to just save up for a better portable projector that has mini/micro hdmi on it
A converter is the only way to go component. It sucks :-( . But if you don't want another power supply, pick up a HDMI to dvi cord and an headphone jack to l/r speakers.$20 bucks at radio shack.

I have seen the Motorola Lapdock being used with some other phones (Sony Xperia?) and even with stuff like an Xbox 360 or PS3, just wondering if anyone knows if the Rezound would work using the MHL HDMI adapter. If it would charge the phone, and the keyboard and touchpad worked, that would be great, but I am primarily just wanting to use it as a portable display during my 12 hour shift at work where I spend most of my time in a parked car.
If this doesn't work, does anyone know of an alternative? Possibly a thin portable monitor that can be run on a battery or plugged into a car? Again, my primary goal is just to output to a bigger screen for video and the occasional websurfing or game, I can always control everything via the phone or like a bluetooth keyboard or something.

Not sure about the Moto dock. I would imagine that you could get an LCD that is made for putting in headrests and whatnot for custom car applications that has an HDMI input and you would be set.

Hmm this is giving me ideas... I was fist thinking of making my rezound dockable with my desktop monitor when ubuntu for android came out, but now im think of making a complete lapdock type thing... interesting.
Keep in mind the charging limitation of the MHL adapter. Because it needs the data pins, they can't be shorted out and in turn the phone will only draw 500mA to charge with, there's a number of complaints about batteries dying while using the adapter as a result.
