I know this topic has been done to death over the years but I haven't used the site for a while and I can't seem to successfully search on MP3 - have older posts been archived?

Anyway I have changed my car to an April 05 525d M Sport with Nav Pro which I will have for a few months.

It will not play MP3s on the CD player. Should I ask for a software upgrade.

Would someone also please advise me how I can change my "ride" details. It isn't obvious to me

Thanks
