I'm currently ripping out my single din radio, climate control and cage assembly in my 2006 A3 s-line, to replace it with a double din cage assembly ready to receive a rns-e later in the year... (Probably my Xmas present to myself!) so, in the meantime, I am looking to put a double din concert radio in the large gap! I have been looking on ebay for a used one to come up, but they all seem to say 2007 onwards? Is it not just as simple as a straight swap, single din for double din? Also is it easy to get a radio code for a second hand set? Is this something I can do with vcds?
