On http://wiki.xda-developers.com/wiki/Connectors it is clearly explained that the MDAII connector has following audio-related pins:
1 CAR_MIC_IN
3 CAR_AUDIO_R
4 CAR_AUDIO_L
With the original T-Mobile MDAII carkit ALL audio (phone & pda) is said to go via these pins
With the XDA2 carkit only phone audio (after accepting a call) goes via these pins.
Maybe this has also something to do with the switching of the in-car signal on
19 CAR_ON
:idea: CAR_ON is connected to +6V on the car charger which makes the phone go to speaker mode immediately when picked up or dialing.
>> This is the behaviour of the XDAII carkit!!!
When this pin is connected to ground, the internal mike and speaker are turned off, and audio input is taken from the audio input pin on the connector.
>>Is this the behaviour of the MDAII carkit??
:?: So: Would it be worth trying to connect pin 19 to ground instead of +6v inside the carkit cradle??
Can't believe no-one with a XDA2 / Expansys carkit is looking forward to solving these issues too . . .
I checked this a couple months ago when I dismantled my expansys car kit. I'm sure I found pin 19 is already grounded on the carkit. With regard to this part of the pin 19 description:
"...CAR_ON is connected to +6V on the car charger which makes the phone go to speaker mode immediately when picked up or dialing. "
"Speaker mode" in this case means the handsfree mode, where the integral xda II speaker is turned up to "distortingly loud" and the internal mike is used in call, similar to what happens if you push and hold the green/send button during a call. If pin 19 is raised to +6V, this will be the xda II's default behaviour with the phone function. This is so you could plug in a simple car charger that puts pin 19 at +6V and that provides only power to the unit (no mike, speaker etc) and allows you to make/receive calls through the builtin speaker and mike without having to hold the xda to your ear.
I feel that if pin 19 is grounded, all audio should be sent through the bottom connector and then into the car kit. Indeed, this is the case with some ROMS / software versions, but not in others. I therefore think it is a software/ROM issue.
I found with my uk o2 xda II, with both the launch ROM and 1.60.50 ROM I got the same behaviour - the unit did not send pda audio to the bottom connector whether pin 19 was grounded, raised to 6V or left floating. Yet other HTC Himalaya owners have reported things differently with different ROMS.
Firstly I thought this to be a s/w issue as well.
But then: The T-Mobile MDAII carkit seems to be working as desired no matter the rom version . . .
Could we get together a list of device/rom/carkit combinations with the actual behaviour in sorting this out?
ANYONE: pLEASE POST YOUR CONFIG HERE.
MINE:
Config: MDAII / 1.60.00WWE and 1.60.36 ext / XDAII Carkit (Expansys like)
Bahaviour: Only phone audio via carkit when in a call
Configs
I am having an identical problem
Build: 13252 - 1.60.00WWE EXT. 1.60.50
I have an XDA I've been messing about with in the car to try to make myself an in-car kit and that was all going fine (Although the phone is now stuck in in-car mode, think i've blown something up ). For the kit I made there, +6v on pin 19 output all audio to the connector.
I then bought an XDA II and in-car kit, wired it all in and then tried to play audio through an in-car cassette adapter lugged into the headphone socket that's built in to my in-car kit. The phone outputs to the speakers fine, but the audio, (Mp3 and the like) won't go to the conncetor at the bottom. (Note that the in-car kit's jack socket is driven off the 22 pin connector at the base of the XDA II)
I'm dissapointed that it could be a softwaer problem, although surely someone somewhere must know a way to force the software into in-car mode constantly and playing the audio out?
Any solutions then let me know cos I'm really irritated that I've just spent £150 on the in-car kit only to find that it don't work yet!
Roll on the XDA-Developers Special Ed. ROM for the XDA II, I bet that'll fix the problem!
Keep me posted on any updates,
Will

not sure how easy it will be to change the dll files over, anyone with some experience in doing this fancy having a go first and letting me know how it gets on? Is it possible to do? What do I have to do once I mess up the ROM on the pda by overwriting a dll file? Can I just hard reset?

every thing seems to be the same
though there are differences in the sound output
pin 19 must be connected to ground for sound through the connector
pin 19 cant be connected to +6v or else the whole xda2 is not responding anymore
pin 1 (mic) must be amplified
going to buy a small mic ampliefier on 12v tomorrow
Hmm, considering people still use their XDA I carkit, i suppose it should work...
However, the audio i tapped from the bottom connector is dead too...
Only hing i can think of is that HTC rewired it so the bottom connector only gives audio if you ground Pin 19 (Car_on).
If your 100% on pin 3 & 4 being #ground, they might have made audio mono, and switched pin 2 & 3, audio out on pin 2 and ground on pin 3. For audio that would still work...
Btw the headset-out is filled with a rubber piece, not handy for quickly attaching an audiopug i'm tinking of cutting it, but that's a bit drastic for a temporary workaround to use audio-out...

You took the words straight out of my mouth :?
All i really want is a Bluetooth handsfree profile !!! :twisted:
tomorrow morning ill try to get it working
maybe if i put +6v to CAR_ON it helps
the phone goes to speaker mode
maybe micfroon will work then to
audio pins are the same
so mic in would be pin 1
i think there is only a slight difference
audio was normally always been put through the connector
not it isnt anymore
**update
the connector is the same
the 19 pin function is different
+ will block every function of this phone, so thats the problem with my own carkit, i have connected it this way
- will send audio only through the connector
problem is now that i want to use a mic
when i connect a mic to pin 1 and GND, there is not sound
i know that pin one really is the mic, cause when i tap the tip of the wire while recording audio or test calling i hear ticks..
what kind of microfoon must i connect to pin one
must the same as the carkit version i think
or what connection will let the xda2 go into speaker mode auto
also there is no audio being put through the connector if pin 19 is not connected to ground
**update
also very intresting and maybe my awnser

I have the opposite problem, i want audio-out for a external speaker, but no ext. mic. (din't get one to work).
what kind of microfoon must i connect to pin one
One that doesn't want a wire to any power.
I bet one of an old nokai headset might work...

Are you sure the wiring is the same, or are you just guessing ?

i am sure
i have tested loads of micrfoons
from nokia headset etc
external sound source is the awnser
i connected a mp3 player and it records fine
now i just need to make an external sound aplifiar for the microfoon
and set pin 19 to GND then its all done
got some old nokia carkit
maybe i can mod it
You mean you got te mic-in to accept audio, but only from an amplified source like a MP3-player ?
Here on xda-developers.com the said the mic-in should't be amplified...
But, hey, they can be wrong to...
when i connect a normal mic (tested 4 different ones) there is absolute sillence
when i connect my mp3 player and turn up the volume then there is sweet sound
Ok, talked to the techie-colleage today :
Headset mic is a condensator mic.
pulls approx. 1V (from audio signal)
What we need is a 'spool'-mic, they seem to be a bit more rare than te condensator ones... these pull approx. 0,6V His thoughs where to use a small speaker and test if it will work as a mic. Then try a real mic...
Or get a velleman kit with condens.mic and amplification
On XDA2 pin2 is NOT GND !
I agree with last post, pin2 in XDA2 is not conected to GND pins 5, 16, 17,18 (all them connected)
When I ground pin2, a little beep (wav) is heard, but nothing seems to happen.
Can anybody point what's the use for pin2 ??
I'm trying to build my own car kit with no success:
I can´t obtain audio out whith or without grounding pin19
I must correct my last update.
I obtain audio when in phone mode, but not during playing waves or TomTom instructions. Even Ring Tones do not go out trough the bottom connector.
So is it a software problem ?
Can function of pin2 br related to this ??
Anybody knows 100% XDA2 connectro pinout ??
myxda web page states that most of the accesories from xda1 will NOT work on xda2
PIN 2 IS ground, or the XDA 1 carkit wouldn't give any sound in combination with an XDA 2 !
The XDA 2 seems to give sound ONLY for phone be it through carkit or BT headset.
If that's true, and if that's the hardware on the XDA 2 then i want my XDA 1 back !!!
is there any solution yet to fix the bad audio quality at the connectors car_audio r/l ?
Hi,
I've got a problem with my carkit (O2 XDA-Carkit) after I upgrade to the new ROM-Version of T-Mobile (1.60).
With the old Rom-Version, the carkit works as a loadspeaker for all kind of sound. The voice-instructions from tomtom for example, came out of the carkit-speaker loud and clearly. Each kind of sound, the device made, came out of the speaker of the carkit.
Now, after upgrading to the new ROM, only the telephone works with the speaker of the carkit. With Incoming or outgoing calls I can use the carkit as usual...the speaker works and the mikro works also. But every other sound (e.g. tomtom voice-instructions) came direktly out of the speaker of the mda2 in a poor quality.
Some hints, how I could use my carkit again as a speaker for all kind of sound without goinig back to the old ROM ?
Any other kind of hints...maybe to use a bluetooth headset therefor (so that all kind of sound came out of the headset....not only telephone...I've got a Plantronics Headset...but also only the telephone works)
thx for help
best regards
rob.
Yep.......I have the same problem here.......don't know why they changed settings on the handsfree profile here.
Another thing you will find out is that the charging is very slow on the XDA carkit with the XDA II. If you run TomTom, Yeti and a bright screen the xda II will not charge, but drain!!
It has something to do with the wiring of the interface, but unless someone will come up with a solution I will go for a new carkit or a BT solution. (It's a bloody shame though it doesn't work properly with the XDA carkit! :evil: )
Hi,
the charging-problem is also a mess.
I think, the problem is only the GPS-driver from tomtom. In my tests, only when the GPS-driver is loaded, the battery-power goes down. With stopping the GPS-driver, the battery will charge again, but only, if the battery-power is more than about 75 - 80%.
If the battery is less than 75%, it will not charge at all, even if, there is no App runnung and the screen is off.
You said, you will go for a new carkit or bluetooth-solution. Do you know a carkit or bluetooth-solution, wich offers the feature, that all sounds (tomtom instuctions...etc.) came out of a loadspeaker or thru a headset (without connecting the wired headphone ;-)
As far as I know, at the moment all devices works only with the telephone-funktion....
best regards
rob.
Same here,
i have build my own carkit, and have put ground to pin 19,
sound was normally going though the connector to my car stereo
now it doenst anymore :evil:
I am sure this isnt a hardware thing it is software
could be the settings on the handsfree profile. on the xda2...
this is very very frustrating. just being finished with my carkit and now i cant use it anymore
also you cant set the phone to speakermode anymore..
I am sure this isnt a hardware thing it is software
could be the settings on the handsfree profile. on the xda2...

Does anybody know how to change this back?
I found that the registry points to a certain file in your windows directory: HandsFree_Dll.dll
(I found this here: HKLM\Services\Handsfree)
Can someone with the old 1.03 ROM please upload this file so i can try if this solves the problem...
TIA,
Max
Akira, Max :
I am building my own car kit, and have no success.
I do not obtain audio out with or without grounding pin 19.
I'm running Rom 1.60.00WWE.
Did you solve your problem ??
I must correct my last update.
I obtain audio when in phone mode, but not during playing waves or TomTom directions. Even Ring Tones do not go out trough the bottom connector.
So is it a software problem ?
Can it be corrected ?
After playing with the idea for almost 5 years I think I am now ready to buy an Intercom for my old bike (1984 BMW R100RS).
My intention with the intercom is to be able to speak with the pillion rider of course, but mostly it is to have the ability to use the features of the Himalaya (Qtek 2020), including:
• GSM speech (from both rider and passenger)
• Audio (directions e.t.c.) from the Navigator software (GPS Bluetooth connected – so there are no issues regarding the GPS)
• Audio when using it as an MP3 player
I want to connect the intercom with the 22 pin flat connector, because I also want to charge the phone, and do not want to have the troubles of connecting two connectors (round and flat) at the same time.
I have had a look on the page: http://wiki.xda-developers.com/wiki/Connectors. Instead of going for the DIY Car-handsfree, is it possible to connect the pins from the Himalaya directly to the intercom unit? The intercom unit it prepared for attaching phones.
Audio Connections:
As I read the description (and if it is possible to connect directly into the intercom unit) I would connect it as follows (since the microphone and speakers will be connected to the intercom unit, the following is the “virtual” connections through the cable into the intercom unit and onwards to the mic./speakers in the helmets):
Microphone:
Pin 1 – Line in
Pin 5 – Mic. Ground
Right Speaker:
Pin 3 – Left Speaker
Pin 5 – Speaker Ground
Left Speaker:
Pin 4 – Left Speaker
Pin 5 – Speaker Ground
Question:
I am not sure about pin 19 (CAR_ON#), but as I read it, it must be connected to ground (not the audio ground), in order to have all audio input/output come from/to the intercom. Is that correct?
Charging connections:
I will be using a 5V (7805) regulator, and connect:
Pin 20, 21, 22 – + 5V
Pin 16, 17, 18 – Ground (and maybe pin 19 – se above)
Question:
The “Power hookup” digram shows pin 15 (UDC-) should be connected to the ground, along with pin 17 and 18 – but not pin 16.
Pin 19 is connected to +5/6V, but the pin 20 is not.
What is correct in my case – the “DIY Car-handsfree” or the “Power hookup” diagram?
Summary:
Have I overlooked something (forgotten connections/wrong connections)?
Will what I have described work as intended?
Has anyone had any experiences connecting the Himalaya to an MC intercom?
The Intercom:
The intercom I have in mind is an Autocom Active-Rider (kit 3). http://www.autocom.co.uk/
Thanks in advance for your help.
Steen
Did you have any success?
I have the MDAIII and want to use it on my motorbike with the Autocom.
Yes
I have used it all of this season, and coversation possible up to 180 km/h - which is as fast as my old Beemer can do.
/Steen
Hi steen, are you still around?
I've just fitted an Autocom to my BMW and I am now looking to connect my XDA IIs to it and wondered if you could help with a schematic?
Andrew
I've just bought an Autocom unit and have laid it out for a dry run. I've fitted the speakers into the helmets and mike boons. When I attached my XDA mini s, I attached it through the headphone jack with a 2.5mm. Trouble is, when I receive a call, Ican hear them but they cannot hear me as it is in the headphone slot. Is there anyway of connecting the phone so that I can be heard, ie, via the mini USB slot.
Thanks in advance.
i think you will find you need a 4 ring 2.5mm plug for the mini s. im not sure which does what yet but will be looking into this soon. i think though it goes from the tip to the body of the plug
tip audio (poss left)
ring 1 audio (poss right)
ring 2 mic
ring 4 ground (common to both mic and audio)
so if you are using a normal 3 ring 2.5mm you will be shorting the mic to ground thus it cant be heard.
All you will need to do then is patch them to the correct connections on the bike system.
Im wanting to do this for myself but im going to build into the connection between the mini s and the bike system a push switch (add the patch to get the talk button to fire up the voice dial) and copy the wiring on the mini s supplied headphones.
I have used it all of this season, and coversation possible up to 180 km/h - which is as fast as my old Beemer can do.

Just bought this car kit http://www.expansys.com/product.asp?code=109748 for my Qtek 2020i (Alpine)
Pretty comprehensive kit for the money. 8) Comes with control box, speaker, mic, loom for connecting to car stereo system.
I was wondering if there was any way to put the audio of TOMTOM or media player through the car kit ?
I have read about the 10K resistor mod which i tried with another active holder i have but that didn't seem to work :roll:
I thought there may be a utility that could fool the PDA into thinking it is in a call and sending the audio through the car kit, but when in a call all other audio is muted.
Are there any other work arounds getting TOM TOM / media player to output through the car kit?
Thanks
I upgraded my 2i to the latest official rom and when i put it in my cradle (looks the same as yours) I couldn't hear any tomtom directions unless i had the external speaker connected to the control box (haven't got mine wired into my stereo so don't know if the voice would come thru the car speakers).
I found that there was a slight delay on the instruction (cut off about the first 1/2 second) and that it kept losing the sat lock (using rikaline wired receiver) every 10 mins or so. Didn't try it with a bluetooth receiver.
The latest official rom wasn't for me (improved blackberry but i don't use it) and I reverted back to pugs one with the camera fixed and the o2 junk removed - now the voice only comes out of the pda's speaker but i don't lose the sat lock at all. There may be a registry hack that'll send the sound thru the speaker but I can't help you with that.
Not a lot of help. Sorry

How hard is it to upgrade ROM's for a beginner, done pc bios flashes b4, but this sounds more complicated.
Is there a fools guide?
are the official ROMS on here?
Don't know why that posted twice - sorry.
Before you upgrade rom backup your data (i use sprite backup and go to the advanced options to select "create self restoring" ones). If you're not worried too much about losing the data already installed then you can use activesync to create a new partnership (you'll have to do this anyway) and restore your contacts from there and any software previously installed.
You have to be careful with tomtom as I seem to remember that after a rom update it sometimes asks you to re-activate it and as you can only do it twice (i think) in 6 months you could end up playing email tennis with tomtom support.
The actual rom upgrade is easy ( I've never encountered any problems but use the search to read up on the procedure before going for it) - just remember to leave it in the cradle with the mains adapter plugged in as well and follow the instuctions.
The only minor hiccup i've had is that the rom upgrade wouldn't run first time round but just clicked on run again and it was fine - good luck
Yeah I have heard that about TT, I am a bit reluctant to upgrade the ROM, seen a few posts "pda dead after rom update HELP!!!" :roll:
Surely it must be doable without all the faffing, hopefully someone will know of a reg hack or a util that will do it!
Thanks for your advice.
You would have thought TT would automatically stick the audio out of the car kit :roll:
Had a look inside the car kit and it's micro circuitry tiny surface mount stuff!
That pretty much puts thying the 10K resistor out of the window. Too small for my big numb xxl hands
OK, this may not be the correct place to post the request but i do.
I am planning to buy a BMW. THis car offers a bluetooth kit to connect your phone to the car, you know this stuff to use your phone while in the car without actually touching it and talking via the car audio system bla bla bla..
Anyway, i wonder if these kind of car bt kits are able to play music from my trinity, too? if not, what other ways are there to listen to music in the car via my trinity?
anybody made any experiences yet?
Thanks for your comments.

I know here are some devices that connect to the audio out jack and emit a low intensity fm signal that can be captured on the car's radio.
I had that for my wizard and magician. But the quality is poor. Besides you would have to buy a mini usb to audio jack converter plus you can not use the mic anymore plus it looks like a nerd had had some time to frickle some cables together...
you can try with the parrot mk6000 here
http://www.parrot.biz/uk/products/parrotmk6000
it's an installation hands free, that includes stereo stream profile (A2DP)
in BMW you can hide too the mic under the case of the original mic location
ah, by the way, it's mooooore cheaper than the original BMW one!
The BMW bluetooth kit is not that great, most stock car options like that aren't, even the dealer will tell you that and probably tell you it's only really meant (TESTED) with Motorola phones. If you do get a BMW with a Bluetooth Kit, you're going to need this as far as phone functionality is concerned when it comes to Bluetooth on the BMW, you're going to need Jetware's Bluetooth Extension found here.
http://www.jetwaremobile.com/
The bigger question is why would you bother, it's not like you have that much storage on your Trinity to play audio for music. A better option instead of investing in 3rd party bluetooth options is to get the IPOD option with the kit, this way you have stereo controls and the IPOD sits in your glove compartment so no wires or anything. Not to mention you could always just burn a CD full of MP3, even my stock BMW radio can play MP3's burned onto a CD.
Trinity and BMW
I have a Trinity with the Dopod Test GPS ROM. It pairs perfectly with the BMW system on my E90 320D with Pro Sat Nav, and all the contacts are visible on the Sat Nav screen...most of the time. Last night I could only find those on the SIM Card, but after driving off this morning they are all there again (580 of them). I haven't tried Jetware but it doesn't seem to need it to work.
The Beemer has a 3.5mm audio jack in the console. Get a USB headphone splitter/adapter for your phone and plug your Trinity into this. It will then play through the BMW system.
Excellent information mate. Thanks a lot. So that means I only need to get a usb to 3.5 mm adapter and everything else works fine.
Thanks again.
I wouldn't put out too much hope.
BMW bluetooth is tempremental to say the least.

My friend you are good... BMW comes with the Ipod connector and you want ot lisiten to muzic from a PDA... i bought Lexus GS300 and it do not have an iPod connector i have to pay few hunderd $ to get it fixed...
life is a ***** you will never get what you want and you will never be satisfied with what you have...
just for your info Lexus GS has the bluetooth phone hands free built in with there mark levinson audio system but its not stereo so i am not sure if the muzic u play from your PDA will be good quality, i tried the FM transsmitter for the iPod but in the end i have to move to cable connection as the sound quality was bad from time to time and i was not doing justice to the 14 speaker Mark levinson system...
BMW bluetooth in E91 320d works!
All,
Bluetooth connection works with my BMW 320 Touring (Model E91 from 11/2006) with BMW stock Bluetooth (Feature SA644) and my P3600 (in fact I have a Vodafone VPA Compact GPS running WM5).
The SIM Access profile is enabled using the HTC-provided application "SAP Einstellungen" (probably in English SAP Settings) on the P3600. The P3600 can be operated using the Steering wheel keys (Volume, Receive/Hang up call, show numbers in SIM on the iDrive screen, browse and call numbers and dial numbers using the speech-to-text function of the BMW iDrive). I have the "basic" iDrive system "BMW Business" without the full maps on the iDrive screen, but the Bluetooth feature is the same for both iDrive systems.
BMW has a phone compatibility list and in that list only the MDA Compact III (that is HTC Artemis/P3300) is listed, but all modern HTC phones using BT 2.0 and the SIM Access profile should do. T-Mobile confirmed to me that this also applies to the T-Mobile Vario II (equals HTC TyTN).
Speech quality is like with my old Nokia 6310i, the only catch is that BMW does not offer a charge cradle for extUSB connectors, but a Car-to-USB charger will do. Also, the BMW has a 3,5" Stereo socket in the Console / Phone cradle area to which I connect the P3600 using a 1-to-3 extUSB to 3,5" adapter, then music can be played back using the built-in BMW iDrive stereo system.
