Hi, This is my first post on this forum and I was just after some help. I have a 2008 Audi A3 and I wanted to fit an AUX direct from my radio, I have rang many different companies (including Audi main dealers) but I've had no luck as they all say Audi's have very confusing wiring. I have the Concert radio in my Audi at the minute and just want some directions on how to go about fitting an aux into it. If someone could reply it would be much appreciated. Thanks Tom
