Can anyone provide me with the pin outs / wiring diagram for the factory phone kit in the A3 (may be the same as other Audis). I have the factory phone prep in the centre armrest, but of course Audi don't do cradles for phones made this century! I am going to make my own connection to a custom cradle, but need to know which are the pins for charging and which for connection to an external antenna. I'm sure there's someone on here clever enough to provide this info. Cheers guys. Alternately, does anyone have an old cradle (for any phone) for the generation 2 car kit that they would sell for a couple of quid?
