I unhook my battery and found out that my radio locked up. Well I didn't have a code for it because the previouse owner didn't give it to me. Audi told me they couldn't give it to me and the dealership wanted to charge me $100. I decided to purchase a new clarion proaudio HU. Since i have a 2000 A4 my buddy had to make me a dash kit. Well, he did an awesome job! I will post pics. Well worth the work.
When I pulled out the audi headunit I noticed a 4 numbers written on the top of the radio. I entered them in the radio and guess what they worked. What security! THey right the damn number on the radio!!!!!!
Well, I'm really happy with my bomb azz ride, yo!
