I have an Audi A3 on order with Navigation (and the 6 CD changer in the glovebox). Can the glovebox CD changer play mp3 CDs or just the CD slot on the Navigation head unit? If anyone knows, please let me know. Thanks.

 

No it doesn't play MP3's, but the navigation head unit has two SD memory card slots for MP3's.

 

What is the sound quality of mp3s on a memory stick? I've got a memory stick portable player, but only listen to it with earbuds.
