either of you have problems with the mp3 playback mis numbering songs?
ive had problems using the 7998, 7897, 7995, 7894, it would switch some tracks around in only 1 folder

for instance, track 5 of folder 3 was really track 17 in the alpine deck, but when i put the mp3 disk in the kdcx959 or 859 (kenwood) it would play it correctly

maybe its just that cd, i never tried another mp3 disc, but i used imation media cd-r 80min and nero to burn
