For those of you who have grounded pin 19 to get sound out via bottom connector, have you seen this site which sells proper car kits for the blueangel
http://www.thb.de/index.html?lang=en
Note the bit at the bottom of the MDAIII car kit about wavedev.dll, could this be the solution to all sound out via bottom connector?
could someone who has already got pin 19 wired up test this before i bastadise my cradle with wiring of XDA II
Audio out at bottom connector
Hi,
I have just finished my work.
I have grounded pin 19 via 10K resistor and then installed wavedev.dll from the site http://www.thb.de
Now it works well. Internal mic and audio are switched to pins 1 (mic) and 3,4 (audio). I have connected the MDA III via bottom connector to my motorcycle intercom and now I can hear all instructions of my navigate software as well I can telefone with my helmet on.
I had tried it before without THBs wavedev.dll and it was only possible to use the telefone function. MP3s and navigate instructions couldn't been heard.
greetings bombur
So are the pin outs the same as the XDAII? if not could you please provide the full pin out, including power and ground
Hi,
yes, the pin layout seems to be the same as XDAII, MDAII (himalaya).
I have been fooling around with this for months now... to what did you ground pin19?
Thanks,
Dutch
I groudeed it via 10 resitor to pins 16,17,18.
But without the wavedev.dll from http://www.thb-service.de/download/MDAIII/Wavedev.dll there is no chance to get audio output from mediaplayer ond so on.
regards
Cheers! I've downloaded the .dll as well. Nice finding!
Did you do anything with PIN5 (ANALOG GND)?
Thanks,
Dutch
I connected it with audio-
Pins 3 and 4 are audi+
regards
I've tryed using this wavedev.dll to see if i've got any luck sending audio (mediaplayer. tom tom etc) to my bluetooth headset but doesn't work... Just tought it could be something with routing the audio...

I have come across a thread which described a registry hack to output tomtom GPS Sounds etc to a bluetooth headset, but i cannot find it again, but this thread in another forum backs my thinking up http://www.mtekk.com.au/forums/viewtopic.php?p=24624 you should root around the google, it is only on one of three sites, this one, MoDaCo or Mtekk but i know its possible at least
Can you make me one?
I have a PPC6600 (PDA2k, XDAIIs, etc.) and I have a couple questions...
When you unhook the bottom connector from your phone, does the audio go back to the internal speaker and microphone?
Also, when the bottom connector is plugged in, what takes precedence, your bluetooth headset or the bottom connector's audio?
Last, if I paid you could you make me a cable that would have the connector that would feed to :
3.5mm Microphone Plug
3.5mm Stereo Audio Plug
Radio Mute Plug (pin 12 supposedly?)
Power?
My vehicle's radio supports RCA feeds and Radio Mutes, and I would LOVE to get this hooked up...
Lastly, is it possible to pipe out video through the connector? (Just thinking about the XDAII backpack...)
Thanks,
Ryan

Hi rleestma,
>When you unhook the bottom connector from your phone, does the audio go back to the internal speaker and microphone? <
Yes internal speeker and mic are turned on when the connector is unhooked.
>Also, when the bottom connector is plugged in, what takes precedence, your bluetooth headset or the bottom connector's audio? <
Bluetooth headset is preferred, the external speeker works but microfone is only used from bluetooth headset.
>Last, if I paid you could you make me a cable that would have the connector that would feed to :
3.5mm Microphone Plug
3.5mm Stereo Audio Plug
Radio Mute Plug (pin 12 supposedly?)
Power? <
The answer is no. I'm glad, that my connector works. But until this I had disturbed 3 connectors because of my very small experiences in soldering.
I think that every TV or radio store could help you when you tell them the pin layout and how to groud the pin 19.
>Lastly, is it possible to pipe out video through the connector? (Just thinking about the XDA II backpack...)<
I don't have any idea how video can be piped out through the connector.

Hans-Dieter
Thank you... Maybe a few more quesitons?
Thanks for the info!
Perhaps a few more questions then?
Where did you find these parts?
1. XDAIII connector
2. Wire to solder in connector
Secondly, do you have some type of diagram layout and parts list for resistors, power, etc.?
I also have very little experience doing this type of thing, but this is EXACTLY what I need for my little project...
Thank you for your help in advance!

Questions on Schematic
Hey there...
when grounding the Car_ON (pin 19) through a 10k resistor, which pin did you ground it to? Was it 15, 16, or 17? The reason I ask is that it seems that incoming power ground needs to be on 15, 17, and 18, so does that mean that the CAR_ON needs to be sent to pin 16?
See what I mean here...
http://wiki.xda-developers.com/index.php?pagename=Connectors
Thanks,
Ryan
Hi,
I bought this connector http://www.haid-services.de/pi-680482093.htm?categoryId=49 .
The Cable and the resistor I got in a tv shop.
One pole of the resitor you have to solder to pin 19 and the other pole must be soldered to pin 16, 17 and 18.
Don't use pin 15 for ground from the car charger. It's only used for USB cable.
regards
Yes, I saw that you soldered pin 19 to pins 16, 17, and 18, but the problem is that the positive lead ties into 19, 21, and 22...
So, with that being said, i have two questions... Did you tie power into your setup? If so, then...
1. Do I tie in the positive lead from the car charger into pin 19 at all because it's going to be grounded out?
2. Do I tie in the negative lead from the car charger into all the pins, or only the ones that aren't being tied back into 19?
If you have an example that you used the worked that would be STUPENDOUS... I feel like I just need to have this quesiton answered and I'll be good to go...
Ryan
Can I use this connector, or do I need to use the other one from you?
http://store.yahoo.com/gomadic-new/ipconplug38s.html
Again, if you used power, can you let me know what pins you tied into the positive and negative? maybe a diagram?
Ry
Hi rleestma,
have a look at http://wiki.xda-developers.com/wiki/Connectors
There you can see that pins 20,21,22 are power+ and pins 16,17,18 are ground. Now connect now solder a 10k resitor between pin 19 and (16,17,18) and it should work.
But only if you download the wavedev.dll from www.thb.de
regards
wiring question
last question...
when you were wiring yours up, did you jump 19 right at the connector or did you run everything back to the opposite end of the cable and then run the 10k resistor?
Also, did you tie in the car charger's negative and all the negative pins together at the other end of the cable, or did you run one negative wire to the connector and then split it there? same for the positive...
thanks!
ryan
Hi,
the resistant fits in the connector, so there is no need to use an extra wire to connect it outside to the ground.
I connected the the pins together with solder in the connector.
regards

The headset adapter will work for both XDA, XDA2 and XDA 2 mini. unless of course you need the answer button function.

I presume you got the $5.65 ones. I've also just found out that the M2000 and presumably all Blue Angels have reversed polarity and a standard adapter won't work, but someone named Dade says:
"If you plug in the adapter to the M2000 and pull it out slightly (About 2mm) then you start getting sound from both channels. The problem is that the plug keeps going back in and the sound returns to mono.
The solution is simple. Get a BIC biro and take the small ink tube out of it. Cut a piece of the clear tube about 2mm long and slide this over the 2.5mm plug. This stops the pug going in too far. (See my photo)
Im sure that this wont cause a problem with the handset but as per usual do this at your own risk."
I'll give that a try once I got the adapters.
:lol:
Works like a charm!! Tested to work on Qtek 1010, 2020 and S100. minus the answer button and mic. of course. but no bic pen method needed. :lol: :lol:

hi Given,
i desoldered the origional headphones from the insides of the ear pieces,then carefully opened up my ex71's and soldered the wire ends directly to the 71's.
the 71's will come apart,just small amount of glue holding them together.but carefully does it.& make sure the phasing is correct,ie + to + & - to -.
hope this helps, chris....
Hi all,
I finally got bored and went one stage further. I desoldered the earphones from my original headset and wired an in line headphone socket (3.5mm) so that I can pug any headphones I like into the headset.
But best of all I can plug in my irock FM transmitter and use it to relay all the audio from satnav/mp3/movies ets to my car stereo and as the microphone is still on the cable I can use it for handsfree...Hooray!!!
Cheers

I've just done this as well. First remove the rubber ear piece.
You need to open up the ear piece by sliding a knife around the edge of the rubbery stuff nearest the ear. This is the same bit that forms the cable shroud. With mine, there was glue for about 1/3rd of the rim.
Then you need to prise the metal speaker out of the plastic. I did this with a knife. Snip off the wires for the Sony leads. Thread the wire from the headset through the cable shroud. With my MDA Vario headset this cable has a woven outer sleeve. I wrapped that in a little sellotape to stop it from unwinding as I pushed it through.
Once the wire is passed through, tie a knot in it to give some shock protection. Trim the ends of the wire and spread the two ends apart. With the Sony earpiece wires one was green and the other was bare copper. The headset wires were red/green and green so I joined the green to the green and the red/green to the bare copper terminal. A small soldering iron will help.
I soldered a socket into the headphones supplied with the BA, but found it gave unequal sound.. one side was muffled. As such, i bought one of the ones listed above.. a lot less messsy too :-D
I'm sick of trying to find a car cradle that has audio out, ps2 and 12v for charging!
Why is it that no manufacturers of xda cradles ever realise that some of us want to listen to mp3's in the car and have tom-tom voice prompts coming through our stereos!
Being right handed, I want my PDA on the right of the steering wheel, so I can operate Tom-Tom before setting off, or change tracks on media player. I did look at the Brodit pro-clip solutions, but they all seem to be for the centre console for my car (a citroen AX)
I've discovered that the driver's side vent mount has a removable panel, which means I can easily mount a small piece of wood (effectively a small flat shelf) for mounting a cradle, this also brings the device out of the reflective glare zone in the windscreen during night driving. It also means all I need is a standard xda iis cradle to do this mod.
So with much careful thought I've decided to do the following:
Buy a spare cradle:
http://www.my-xda.com/xda2s_other.html
Which leads me to the next question....
Has anyone got any modding experience with the xda2/xdaiis cradle?
similar to this old posting for the Wallaby...
http://forum.xda-developers.com/viewtopic.php?t=256&highlight=cradle
(although I couldnt see any of the images on this old posting!)
In theory, this project has 3 key issues to resolve...
1) Powering the cradle and Bluetooth GPS
Three options seem to be available...
a) The hobbyist approach...I've seen various "car-kit diagrams" like this one,
http://forum.xda-developers.com/files/xda_car_kit_circuit.jpg
but to be honest I have no pcb making experience.
b) 12V to 5dc cigarette socket transformer adapter to provide power to the cradle, and perhaps to the bluetooth gps for charging. This should be easier to achieve!
Anyone have any links for low cost solutions for this, obviously it would need to convert 12VDC to 5DC at 2-3Amps
c) As the xdaiis usb cradle charges directly from a USB power source, this seems an Ideal solution!
http://www.expansys.com/product.asp?code=EXP_USB-CLA
2) Audio out: THE MAIN PROBLEM!
Ideally I just want to get in the car and cradle the device, no other connections being required.
Therefore I need to modify the xdaiis cradle for audio output...
Ideally, the feed for the audio should come from the bottom connector, when the xdaiis is cradled.
With this in mind, I found this article about dismantling an xdaii cradle...
http://en.pdamobiz.com/en/forum/forum_posts.asp?TID=42&PN=1
If you look at the images on this web-page, you can see that - at the back of the cradle on the opposite side of the usb cable from the 5volt dc input is what looks like a pcb pinout for a headphone connector...
is this right? Can anyone confirm this.
Would it be possible to solder a connector onto here (assuming the solder pads connect to the 22pin connector!)
As this would be far easier than mucking about trying to solder onto the miniscule pins on the bottom of the 22pin connector on the cradle as it goes into the pcb!
If it works of course!
b) modify a headset
I did consider modifying an old wallaby headset to wire it into my car amp
http://wiki.xda-developers.com/wiki/Connectors , does anyone have any info on the pinout for the himalaya/blue angel headphone socket? I have also tried a friend's xda II headset on the IIs and yet again they have changed the pinout! The audio connections are once again totally different, resulting in the "echoing" effect when one headset is plugged in from the other device. This means that the audio ground pin has changed since the xdaII headphone socket schematic! This difference is also confirmed by looking at the handsfree "pod" on both headsets... The IIs has one button for answering a call, where the II has two buttons, wether it is the same as the XDA1 (Wallaby) remains to be seen....
c) buy a PDA2k 3.5mm headphone adapter...
http://www.expansys.com/product.asp?code=118289&sbadd=118289
Then use a standard lead to connect it to the hi-fi amp in the car.
3) charging the TOM TOM BLUETOOTH GPS
I'm wary of putting anything other than the recommended voltage (5VDC) into this device, so the best option is to supply power using (1b) or (1c) above, perhaps cutting into the supplied RJ cable to minijack psu to hook it up from the same supply.
While I'm on the subject of the bluetooth gps.... Does anyone knopw how long does the tom tom bluetooth gps work with a full charge?
Does it vary based on an active connection, or is it the same as on standby?
Do I need to power it in the car at all? Can I not just charge it as required at home? There doesnt seem to be much literature about the Bluetooth GPS reciever's battery life in the box!
Anyone care to comment on these ideas?
:lol: :lol:
I think the fact that no-one makes a cradle which provides audio-out through the bottom connector of the XDA2 is because the XDA2 doesn't provide this possibility. It's not the car-kit manufacturers' fault. Blame HTC.
However, I could be wrong... :roll:
My solution: I bought one of these XDA2 mounts ( http://www.pdamods.com/proddetail.asp?prod=A11XDA2MNT&cat=23 ) which works really well. It charges the phone and my TomTom BT GPS. To achieve audio-out I plan (eventually) to use the XDA2's headphone socket by drilling a hole through the mount's base in the right spot and using a 2.5mm jack adapted to play through the car stereo. Not an ideal solution, but surely must be simpler for you than trying to build a reliable (and safe!) 12V -> 5V convertor and butchering a spare XDA2 desktop cradle?
Just a suggestion... 8) Let us know how you get on. Good luck!
QUOTE 12V to 5dc cigarette socket transformer adapter to provide power to the cradle, and perhaps to the bluetooth gps for charging. This should be easier to achieve!
Anyone have any links for low cost solutions for this, obviously it would need to convert 12VDC to 5DC at 2-3Amps
Just about any mobile phone car charger will do.

That's what I'm looking for. Have you found anywhere to actually buy them? I looked over the whole site.
How about this alternative cradle. I bought one for my XDAIIs and it works perfectly. Got one for the birds XDA2 and that work great too.
It provides power to either a wired GPS or charges a bluetooth GPS, it has a built in speaker and a cables provided to run from the XDA's headphone socket to the cradle. THIS THING IS LOUD!
One word of caution, the speakers in my car are shielded so I don't get that warning noise from them that I am about to get a call or text. The speaker on the cradle is NOT shielded and so you do get interference when you are about to get a call or switch cells.

i thought about using my 6601 as an MP3 player in my car as well. but since my eclipse cdplayer does mp3, i abandoned the idea
option 1: cut up a 2.5mm headset and plug it into the top of the device
pros: cheap and effective
cons: have to plug it in every time (and unplug it to take a call)
option 2: pair a bluetooth headset with the device, crack it open and wire the speaker to a preamp
pros: wireless
cons: ruin an otherwise good bt headset, music would be in mono
option 3:
http://motorola.digitalriver.com/se...e&SiteID=motostor&productID=36065700&Env=BASE
"transfer audio to hands-free"
pros: wireless
cons: EXPENSIVE, pretty vague description
option 4:
http://www.itechdynamic.com/html/border22.htm
http://xprnnews.xfn.info/itech/nightingaleBSH338/en.htm
pros: wireless, stereo, routes incoming cails through car
cons: i cant find it anywhere
its called the "nightingale BSH338" or the "Bluetooth Stereo Clip Headset"
if anyone finds one, please reply with a link

Hi,
Dunno if anyone is interested but I now have DAB Radio plus ANY selection of music that i choose BLASTING out of my home stereo.
Finally got round to cutting off the ear buds from the supplied headset and replacing them with Phono plugs. Now I can plug Lobby into anything.
I, incidentally, was lucky enough to get a really worn set of headphones with my lobby and complained to Virgin & got a spare set.
It's a 5 pole plug so I presume one of them is the DAB aerial, when you stripped cable was their 5 wires?
Does your cable now work fine as a aerial (I presume so)? If so how did you break that out?
Do you live in a area that has a good DAB signal.
Any pics of cable?
Cheers - sorry for all the questions!
Hi.
I simply nipped the two ear buds off leaving all the connections in place on the plug so the arial didn't get disturbed.
when you carefully strip the cable you need to separate the sets of wires. they are NOT plastic sleeved, but they separate quite easily. Then set fire to the ends of them and let them burn back for 40mm or so. this will expose the copper ready for soldering. Note the common colour goes to the earth and the other colour goes to the centre of phono plug.
I have no idea which is left or right but someone on here will know I'm sure.
(I just guessed)
My area isnt good for Dab anything.
gave up on the TV bit ages ago.
If you look at the back of phone there is a removable plug for an external antenna which leaves the front socket for phono lead.

As far as I know this is the GSM antenna socket, not the DAB radio antenna.

Hi there, I have a 2nd hand Blue Angel, and after looking continuously over the pda could not find the headphones jack, as the auctions I looked at said 2.5mm > 3.5mm, so finally found out i'm missing the lil jack thingy.
Am looking to purchase the jack for the bottom of the pda
Please PM me as I will probably not see this thread all the time.
Question: is there a funny usb little plug that goes in the bottom (into this plugs your headphones)? well this what i need.
cheers!
IIRC, the headphone socket is on the top left of the BA. It'll have a little rubber dust cover on top of it.
It isn't a standard 3.5mm socket though, so either get the smaller (2.5mm?) headset or get an adaptor so you can use 3.5mm headphones.
I've got a BA stereo handsfree kit for sale here...
http://forum.xda-developers.com/showthread.php?t=497241
yes, it is 2.5 mm, since mine broke the other day i also researched a bit and found out that adaptors don't really work, we had this discussion in this forum before, the connector layout of the ba's plug is not standard, so if you take an adaptor, you probably won't have the full comfort of an original headset, like proper stereo, ptt..., maybe the mic won't even work. there are also a lot of other branded headsets out there, that seem to have 2.5mm and 4 connectors. so always test handsfrees before buying
HA! great stuff, it was hiding lol, I swear I went over the device numerous times searching, then just assumed there was an adaptor for the bottom (where the dock plugs into- the usb type thing).
thanks guys,
I was at work the other week and had a slight problem.. how the hell do i get music from a TG01 into a sound desk.. I tried to use the micro USB to 3.5mm adapter with a 3.5 to 3.5mm cable into the desk AUX input, we also tried using a 3.5 to RCA cable... the final thing we tried to make sure it wasnt a problem with the desk was to go straight into the DJ mixer using a 3.5mm cable. nothing worked. but Iphones, Ipod, other MP3 players all work using this method...
any ideas folks?
Have you tested the supplied USB to 3.5mm with a normal earbud? do you get sound out of it?
The USB to 3.5mm cable is just a simple Analog Left/Right/Ground port and so it should work with any Stereo plug regardless of the destination
I suspect that the USB to 3.5mm you used is busted
you can also use a bluetooth adapter with 3,5mm plug, the one i use was 32,- euros and works perfect

Not at all.
The TG01 does require a certain resistance to be presented to the device and it is this which it interprets as to how to respond.
If the two data lines D- and D+ are shorted, it will go into Charge mode. If it sees a resistance of around 20 Ohms or more it will switch the audio output to the micro USB port. Typical earphones will have an impedance of around 30 Ohms, while the input to many battery powered external speakers is 4 or perhaps 8 Ohms (ever lower on amplifiers). This is why your TG01 worked fine into the earphones but not your external feed.
This texts it's not mine (just the blue one). It was written for the great kevinpwhite, on MODACO some time ago. And it's true (I've made the resistor modification in a set of stereo amplified speakers than failed as Tomsutton said and now they work perfectly.)
You can read the full explanation here: (I'm xdalover on Modaco )

This texts it's not mine (just the blue one). It was written for the great kevinpwhite, on MODACO some time ago. And it's true (I've made the resistor modification in a set of stereo amplified speakers than failed as Tomsutton said and now they work perfectly.)
You can read the full explanation here: (I'm xdalover on Modaco )

Have a nice day

Cheers pete, Il dig out the specs of the desk and see what the resistance is, I dont remember it going into charging mode though..
Why would an Ipod work but the TG01 wont?

If standard headphones works and aux IN don't work, no doubt. This is the origin of your problem

Easy, an Ipod has a dedicated analogic output. Instead TG01 has a shared USB port with different uses...
Noticed this on mine when I wanted to play music from the phone on my stereo. VERY annoying, and a bit daft of them to do this, even though it's a shared port.
There should be a software option to enable the usb port for purely sound to allow it to pass it across. I see the hardware resistive work as a workaround not the solution (although well done on getting it working!!)
no way. toshiba support:
"There are no settings available on the phone in order to set up the electrical resistance."

I was at work the other week and had a slight problem.. how the hell do i get music from a TG01 into a sound desk.. I tried to use the micro USB to 3.5mm adapter with a 3.5 to 3.5mm cable into the desk AUX input, we also tried using a 3.5 to RCA cable... the final thing we tried to make sure it wasnt a problem with the desk was to go straight into the DJ mixer using a 3.5mm cable. nothing worked. but Iphones, Ipod, other MP3 players all work using this method...
any ideas folks?

With thanks to Pere for the kind words above re. my earlier explanations on this subject on MoDaCo....
....in addition, please note that all of these charactaristics are an intentional part of the micro USB AB 'On The Go' port design and will become increasingly the norm as more devices adopt uUSB.
There is at least one chip being manufactured, but as yet not available to individual purchasers, which will support an external plug in device capable of providing intelligent charging combined with concurrent audio out. Sort of configuration applicable to eg. a car hands free scenario. I imagine that such add-ons will start to become available in due course - this is one of the drawbacks of choosing what is still a leading edge device well over a year after it first appeared !
For the mixing desk input, I'd suggest using an isolating transformer (eg. these here) as the ideal means of coupling - this will provide the necessary impedance (typically >10kOhms) to make the TG01 respond with an audio output while also ensuring electrical separation and maintaining as high quality audio signal as possible.
