On the indash CD to navigate across folders you apparently push the "m" button and then the next track button.

So TR01-01 which means Folder 1, Track 1

would change to

TR02-01 which means Folder 2, Track 1

I checked my notes again on the AUDIOTEXT, and I believe I gave you bad info ... apparently no AUDIOTEXT with the in-dash CD ... sorry !! I updated the top of post, so as not to cause confusion when someone re-reads !
