I currently own an '07 A3 with the concert radio. Which much to my surprise doesn't play mp3's SMH.

I don't want to go with an OEM radio and would prefer to keep the audi stock look. Does Audi have a radio that will read mp3s that I can install in my car? Also does my car support double din? I don't think so but I just wanted to double check with someone who knows better.

Thanks for any help in advance.
