Install question.....I recently purchased an 8E0 035 192 C for my U.S. spec 2003 B6 A4 and wanted to know for sure if I will need an adapter harness or not? I have done multiple searches and am a bit confused if I need one or not? Some folks have said that it is plug and play, however is that with the existing wiring from behind the syphony radio system or do I need to order one from KUFATEC? I installed an OEM VW CD based unit in my friend's R32 and that of course required a bit more labor and some adapter pieces. Additionally, I plan on ordering a VAG-COM unit from Ross Tech, but until it arrives, will the unit work at all after install, or should I wait until the tool arrives? I currently live in Europe so I do not need to worry about adapting a U.S. DVD at this point. I plan on installing Westeuropa 2004-0080 DVD and hope that it will work. Appreciate the help and hopefully I did not miss something already posted. Thank you.
