Hi, Bit of a silly question, but does anyone know if this iPod adaptor would work on a 2006 a3 sportback. Ebay Item: 130081162327 It mentions that it works with a Concert radio (which I have), however doesn't explicitly mentoin the a3? Is there a difference in the Concert stereo fitted to the a3, to any other Audi? Any help would be great. Rgds, Brian.
