Dear All, I would be really grateful if any of you knowledgeable souls could give me some pointers about car kits in the new A3. I am getting the Symphony II radio which I gather will have the new 'Quadlock' system fitted with a 40-pin connector. Is there a pin-out for this or a pin to connect a mute lead from a car kit and are there marked pins to connect the car kit's speaker output to go through the car speakers? I gather from elsewhere that something needs to be 'activated' by the dealer in order to allow stereo muting, but I cannot find any information on the specifics. Has anyone installed a car kit in their A3 or had this done? I would be grateful for any info/pointers. /ubbthreads/images/graemlins/smile.gif Many thanks, Toby.
