i dont know if anyone ahs noticed this before. I had a xda 1 and the o2 car kit. i fitted a switch on the radio mute, and wired the kit,s speaker jacks into my stereo,s aux input. this allowed me to listen to wmp, or any other app. Then i bought an xda2 and everything went wrong. so i decided to try sort it out.
My plan was to modify the car kit to accept the phone, and cut out a notch so that i could use the headset, and cut it up and wire it direct to my stereo,s aux input.
however, after i did the cradle mods, i had the phone sitting in, testing it. At this stage my kit was still wired as per my xda1. The phone works fine, including mute. Then, i tried wmp. As reported , there was no sound. I then plugged in my headset, whilst the xda was in the cradle, and IT WORKED!. Sound from the wmp went out via the car kit and into my aux input! I Bought a new2.5 jack, with no wires, and i just insert it, before cradling the phone and i have the exact same functionality as the xda1!...its really kool, as my Haicom gps works fine too. I havent tested Fonix, ie., does the mic work before u activate the phone, but im hopeful.
Now, my final problem is the charging issue, and id appreciate advice. My proposal is: to purchase an appropiate universal lapto car power adaptor,
To purchase a 9 pin lead, which will sit between the carkit and the cradle lead. Then all i have to do is patch the power adaptor into the 9 pin lead, deleting the original power. Will this work, and what size power adaptor will i need [v/curent], and whats the wiring mod?........id love to know if the headphone jack trick works on all kits/.....it may be posssible to buy and modify a jack plug so that it fits in wiyhout modifing the car kit....

re the charging issue
ok..ive read all posts concerning this issue and there appears to be some confusion....can the original xda car kit supply enough current to satisfy an xda11 and wired haicom gps. Some posts imply that there is a wiring difference which makes the unit appear to be charging whilst there not, whilst some posts say its because the original unit can only supply 1 amp.......can someone please advise?
I gues you have to get the 2.5mm plug out when you leave the car in order to use the mic/speaker?
charging issue
ive just tried the unit in the car, both with and without the haicom connected. both times it said it was charging, but both times the battery level actually fell.....this indicates that there is a wiring difference between XDA2, in the charging cct. funny thing though is that the xda2 charged using a cheap cigarette lighter type charging lead....can anyone explain this?
must be the charging circuit. I found that even a 400mA charger is enough to charge the Himalaya.
My XDA II Car kit has a jack plug on the bottom, but if I use that no sound comes out. I'm assuming this takes audio out from the 22pin connector at the bottom of the XDA II.
When you say you've plugged a 2.5mm jack into your XDA you mean the socket on the actual XDA itself right? And that enables audio through the 22pin connector or does it just output audio through the jack?
My problem is now that I'm going to have to rip my (very expensive when I bought it) XDA II Car kit to pieces to put a 2.5mm jack into the bottom of the phone when it's in the car kit!
Is there nothing at all that anyone's got to force the XDA out of in-car mode or anything or is that completely hard-wired?
God this is annoying! Why is there always something wrong, even with the coolest gadget in the world!
I have the same problem.
It used to work with rom 1.03 (as I remember) but after an upgrade, the sound from MDA2 except phone call went through the build-in speaker.
HTC knows this problem, but dont do anything about it.
A conspiracy agains carkit mod'ing.
This issue is known since approx last april.
It MUST be the carkit:
XDA2/iMate carkit only supplies in-call phone audio via the carkit speaker
MDAII/Qtek2020/Yeti carkit supplies all audio via the carkit speaker (dis-advantage: It continuously mutes the radio when ie using TomTom, but that can be fixed by using an alternative radio-mute circuit/switch)
Both carkits only use the 22-pin bottom connector of the Himalaya to accomplish this.
Until now (afaik) no one has succeeded in finding a solution for this.
I wish I bought my carkit 2 month later, at that time the MDAII carkit was sold for approx 170 euros (compared to the 140 for the XDA2 carkit). The extra functionality is really worth the extra 30 euro.

A few weeks ago I bought the MDAII-carkit and am still preparing to install it in my car. I will use it with Alturion navigation software, but expect that this will create the same proble as TomTom (constantly muting the radio).
Could you elaborate on the "alternative radio-mute circuit/switch". I.e. how to create it/where to buy it?
Thanks in advance, regards

You can buy an audio-mute box.
You place it between your car-speaker leads and connect the carkit audio out to it (mono or stereo).
As soon as the mute-box detects a signal on the carkit audio out, it switches the car-speaker from radio to carkit.
It seems to work quite well, but since it is based on detecting a signal an then switching, i can imaginge you lose frist 1 or 2 seconds of the carkit-out.
No idea how that works out with TomTom . . . .

Check pin 19 of the plug wiring. This is the pin used to tell the XDA II it is in the car. When using the XDA II out of the car, in the Sync cradle etc... this pin is tied to ground.
I am about to experiment with making a car kit... If I have success with the audio, I will let you all know!

Audio mute with MDAII-Carkit
@edsub
Thanks, eDsuB, I get the principle and will look around where I could get the audio mute box.
And now I understand why Mocki in the german forum of ppc-welt inserted a one second 63 Hz tone at the beginning of the TomTom-audio files:
http://www.ppc-welt.info/community/showthread.php?t=40190&page=2&pp=50 (in german)
It would be embarrassing to miss the first three words of the message "in three kilometers turn right" :lol: .
How do you think about another solution on this forum and that is disconnecting pin 9 (orange/white) from the connector on the MDAII Carkit II. Apparantly that would also solve the problem with the permament mute of TomTom? See thread (it looks like you've been there also) http://www.ppc-welt.info/community/showthread.php?t=47131&page=1&pp=28 (in german).
Thanks very much,
Albondigas
I went in that forum a couple of times (especially when xda-developers was down), but since I have an XDAII/iMate carkit my problem is to get all audio thru the bottom connector . . . .
And even Mocki doenst have an answer . . .
Hi all
I have a problem with my xda exec, I have lost sound in the internal speakers works through the handsfree kit but nothing will come out of ither the stero speakers or the speaker for in call use.
Does anyone have any ideas?
Thanks

No Audio From Internal Speakers - Solved!
Not long after i posted had an aditional thought, it hadn't been a problem until i had used the handsfree kit, quick blow in the socket and it worked! Must of been dust in there.
No audio - solved!
Hola,
There is a problem with the 3.5 phone jack, suddendly doesn´t work for dust but the quality of the internal components is not good, this problem occurs also with htc s200, please go to the s200 forum and will see some ideas.
In my particular case, I had also this problem in my v1640, I had to open the phone to repair the internal legs of the jack, after that I used again the phone and the problem came back, now I do not use the jack
Saludos
Same Problem

I'm also suffering with the problem is there any solution?
Please help.
Hello averybody, I'm new here. Please help me, my O2 XDA Atom cannot play sound. Someone please help me....
No sound problem
Hi
This normally happens when the headphone is plugged out. There is a small microswitch inside the headphone socket to detect the unplugging of the headphone.
Try inserting a pin and gently moving inside the headphone socket. This releases the switch and audio is back to external speakers. It worked for me.
Hope this helps
May have to send my Desire back to TMobile. Supplied headphones do not work. There appears to be loose connection inside handset. To hear anything I must hold down jack connector and then the volume is very low, the minute I stop holding the jack it drops the sound. Anyone else finding this build issue?
Also the remote on the headphone cable will not operate. I did try the supplied headphones on another device then its o.k. so it must be the actual Desire at fault.
Your phone is probably ok!
I had exactly the same problem, but it's due to the headphone connector.
You should use a 3,5 stereo jack with 4 contacts (TRRS) instead of a the 3,5mm stereo jack with 3 contacts (TRS) which is present on all casual headsets.
You can sole it with an adapter cable.
More info in this forum: topic 6269599 and 667240
My remote doesn't work on my Desire too. But my remote on a friend's Desire works.. grr
Thanks for the replies. Fair play to T Mobile they exchanged my phone no problem. New phone now works perfect. So pleased I got the Desire.
I found a solution for mine, it was tunewiki which override the headset buttons by default.. <clever>
Hey,
yesterday I bought an aux-cable for connection my phone with my car-radio for using the speakers for making calls (because the intern desire speaker quite sucks). i can clearly hear the other person but not the other way round. it seems that my desire is recognizing the aux-cable as a headset and in consequence deactivating the intern micro. any other (software) solution than cutting my headset apart and solder it together again with the aux?
big thanks in advance, jakob
I'd like a solution myself, either...
