9100 2.5 audio pin out

[canstb]

whether I am "search" disabled or there is no info about audio 2.5 jack pin outs.
will somebody give a link or provide connection diagram for mic, answer/mute button and audio outputs?
my aim is to make my own cable to connect the pda to car stereo to listen mp3s and also place a remote mic and switch somewhere in the car.

thanks a lot to whom gave me info about this topic. Here is what I have done today;

I bought an after market 2,5mm stereo headphones with mic and switch. it was 5 YTL equvalent around $3,5. I had the chance to try it with my qtek9100, but there was very poor sound level and quality, I didnt even try the mic. Actually I bought it just to get one 2.5mm 4 conductor jack.

I tried to make a drawing how the connections were, marked as "before". It is so wierd wiring that I have no idea which kind of device uses this kind of connection.
After modification, as you will see, instead of soldering the existing ear pieces, I soldered a female 3,5mm jack, so that I can connect whether a stereo headphones to use it as hands free or a casette adapter to use with car stereo and listen to mp3s(which in this case, when I receive or make a call, it will mute the music and give other sides voice to car speakers). Ive tested both possibilities and it works quite fine.

I hope this helps to ones that are willing to make this kind of adapter themselves.

AFAIK pin 4 - left channel, 3 - right. So U have reversed stereo sound or wrong picture female connector.
