I have tried several times to burn a cd to play in my changer (I have a 99.5 with the Concert radio/6 disc changer and the Bose) I'm guessing that the problem is that the files are mp3 files, so I tried using a converter that seemed to say it would write the files onto the cd as a regular audio cd file, but again I get the dreaded "ERR" message when I try to play the cd in the changer. Does anyone here know of a method or particular software that will let me take these mp3 files from my pc and burn them onto a cd so I can play it in my B5?

 

Use itunes and burn as an audio cd

 

i'm runnin the ghetto mp3 player hooked up to the $5 cassette/mp3 converter haha
works damn good!
