Hi, I have my 2003 Audi A4 for over a year now and I think its time to change the good looking but featurless radio that is the concert headunit in my car. I was wondering if you guys could link me to a diy maybe or if someone could guide me through it because I lost my mind trying to look for answers a google. Will link pictures of the little diagram on top ot the radio and the wiring. Thanks you in advance! http://imgur.com/a/7oczd
