I bought my first audi a couple months ago and it has a standard head unit in with no aux, just fm radio and cd player. I want to change it to an aftermarket one. This one. I was wondering what else i would need to do it (fro example any other wires) and how i would go around doing it as i want to do it myself. I dont really know alot when it comes to this so any info would be helpfull. I have an audi a3 8p pre facelift. 3 Doors Thanks in advance.
