Treba to pomuze... http://www.ajusd.org/~edward/vwcdpic/ The VWCDPIC is a "lock pick," if you will, that unlocks the CD Changer interface by sending the required data stream, fooling the head unit into thinking a real Volkswagen CD Changer is connected. With a VWCDPIC, you'll be able to connect any audio device up to your stock OEM head unit V.
