hi there new lad here I bet this has been done to death but hey hoe
I currently have an A3 8P 2009 (facelift) with a concert ii+ ( I think ) double din with AUX by hand break. very basic and a bit boring so id like to install RNS-E unit or something similar.
what id like to know is, is it a straight swop or is there a bit more involved? also my aerial is in the rear window, I hear some units may not pick up radio stations or not be compatible due to aerial type etc.
