im sure there must be a topic on this but cant seem to find it in the search. is there anyone who can fit a RNS-E to my 2002 S3 for a sensible price? the car only has single din so this would need changing. I know they had an RNS-D fitted factory but i have been told for a bit more money its worth upgrading??? im aware that the climate control unit needs dropping and possibly trimming and would possibly have a go myself if there is a decent how to somewhere?
