ive decided to upgrade my current concert gen 1 for a gen 2. at the moment i have to turn the hu on manualy so im guessing its non canbus. im looking for the part number of a gen 2 that will fit perfect in my facelift s3 with no colour difference. ive been told the 8p0035186c is the one to look for but browsing this section ive read otherwise, so i havnt a clue which one to pick. im rather eager to get one so would appreciate any fast response. i want the system to run like it would out the factory so what else will i need, i also have full bose. please help
