New Audi A3 & phone car kits - help please!

Dear All,
I would be grateful if someone more knowledgeable than myself could give me a few pointers here.
I am informed that the new Audi A3 has what is termed a 'Quadlock'
connector for the stereo (in my case a Symphony II), which has 40-pins. I would like to put a phone car kit in. In my old car this was fairly easy and I took power from the lighter socket and ignition sense from the radio and used the included small speaker. I was also able to put the mute wire into the back of my stereo.
However, I have been unable to find any details of the wiring for the Symphony II with this new style connector. Therefore I don't know if there is an ignition sense wire or whether there are connectors to run the sound through the car speakers.
I would really appreciate it if anyoneone could shed some light on this and give me a few tips!
Many thanks,
