I have a 2002 Avant that I am considering retrofitting a NAV unit into. I found this site thru Audi World but with a quick looks around I didnt see a clear list of things needed or the dif. between the US/EU units and the pros and cons of either.

Sorry if this is overposted topic... I'm a performance guy and have no idea when it comes to electrical stuff... I just "hope" it works.

TIA, Chris
