I've just had a Sony CDX-T70MX changer installed in an Audi A6, with an
adaptor to make it compatible with the Audi Concert head unit. When playing
mp3 files that I've burned to a CD, I find that the changer will play the
mp3 files OK, but if I try to skip to the next track or go back to another
one, it just goes back to the first mp3 in the list and starts again. It
doesn't seem to recognise folders, either - just plays the mp3s on the discs
that are not in folders.

Is this something just have to put up with? I know these things happen with
mp3 players, but I was wondering if it has anything to do with the method I
use to burn the CDs (Roxio Easy CD creator). Any tips or advice
appreciated.
