Thanks for replying maxshelor, I agree with everything you've said, however it doesnt help me much.
The CD in the CD-changer in my car is burnt with 6 directories (albums), each containing a number of mp3 files (songs) with ID3v2 tags.
When the cd is playing it starts with the first directory and first song. (TR01-001) When you press the skip button it plays the second song in the first directory. (TR01-002) In order to play the first song in the second directory (TR02-001) you have to push the skip button 20 times (as there are 20 mp3 files in the first folder)

I was wondering if there is another way to go to the second directory, and came across the mentioned picture on bimmernav.com.

Problem, I can't get this to work, I don't know wich button to push to get to the next directory, or if it is even possible with my setup. Perhaps this works only with an 16:9 monitor, or with a different cd-changer or BM54 radio.

Hope anyone knows.
