Can anyone tell me if there's a method of connecting my Zen Touch 20Gb to my 3 series audio. I have the 6 disc changer fitted in the boot already but may consider disconnecting if I can utilise the audio connection. I've tried using an FM transmitter but it's a bit tooooo hissy for me. I've thought about using a cassette adapter but it would be a last resort. Finally can anyone advise on how to remove the 3 series head unit.
