One of my female friends own an Audi A6 1999. She says her car doesn't have a CD changer, and that her headunit is a tape player. She went to me for help on installing an aftermarket headunit. We went to BestBuy and bought a headunit. I don't think she cares about quality.. she says she just wants to listen to CD's asap. Anyways.. bestbuy just told me they can't do it cuz it needs special hardware, and that the special hardware won't be able to be shipped to their store. They say that I have to go to the Audi Dealer and pickup that part. (I have no clue what the hell he was talking about since this is suppose to be an aftermarket install, so I don't know why he brought up the subject about the dealership). I install car stereos in all kinds of japanese cars, but have never installed one in a European car, and I also don't want to screwup my friends A6, so I need a little help. - I assume I need harness connectors - Faceplate adapter since the factory looks wide. - Do I need special antenna connectors? - And mainly... what is involved in removing the factory headunit? Some cars require to remove the entire center console, or dash, yet others only require a special tool to remove the headunit (simple). I did some research on this forum, and notice that some Audi only requires special tool or DIY nail filer way. IS this the same for the 1999 Audi A6? thanks for the help. If you need any more info to help me, let me know what you need to know about her car. thanks.
