Hey guys, after finding out I am in £1000 credit with Southern Electric I have decided I'm going to treat the Audi to RNS-E Could any of you in the know tell me which is the latest RNS unit that will go in my 2002 8L S3? I know I need an A4 unit (8E0 035 192) but which suffix? Also the new version with piano black surround won't work right? As trivial as it sounds,I'd like one with the silver knobs,which suffix letter is that? Any info you can give me would be greatly received,I've trawled for hours! Lastly, if anyone has a double DIN cage for grabs (8L0 058 005A) please PM me. Thank you Morgan.
