Hi, new to the forum and new to Audi ownership. We have a 2006 A3 Sportback with the single din cassette player and factory CD autochanger in the glovebox. I'm looking at replacing the head unit with something more modern if possible? Something with microSD or USB input and bluetooth if possible. Also it would be nice to retain the CD changer connectivity as well, although I assume this would be a bit of an ask? Any suggestions please? Thanks.
