Thanks davidr,

I did try making a MP3 CD with a range of ID3 tag versions, but this didn't work at the time. It may be that I confused the poor thing and it decided not to play! I keep meaning to try again but never seem to get around to it. Some have had success using the default ID3 tags (v2.3?) on iTunes.

I was dropping my wifes 330ci conv, off at the dealer this am for a service and asked what the display problem could be. Blank looks all round! MP3? ID3? Audiotext? I was clearly speaking alien! After much explaining they reconed the CDC wasn't sending the info to the head unit. (Since the audiotext option is only available when playing the MP3 discs the CDC must be sending something to the head unit.) Much more info on this site.

I will try the ID3 v1.1 tags again.
