Just after some advice on this as I have never used vag-com to code / make adjustments before - only ever used it to scan for fault codes. Basically I am upgrading the factory audio in my 2002 A4 from a Symphony II, to a Symphony II+ I have found the following on the net; Audi Radio Generation II Plus - Ross-Tech Wiki The new unit is from America, so I need to change the country to Europe. The car is a 2002 A4 Avant TDi with material interior, so im guessing I will need to change to; wagon/avant and diesel engine. My issue is, I dont know what 0xx0xx? means, or how to get there and how to change it. Im taking it I go to the "radio" section of vag-com, go to adaptation - from there im lost!... Any help would be appreciated. Thanks.
