Mine seams to play disk 12 over and over. Read manual and it tells to change tracks. Going on trip this summer, would like to get to the other 11 CDs

 

Select the Random mode... that'll get you to another disk.

 

Press the number 5 button, that selects the next disk. It's in the owner's manual. (That is, if it also has an indash cd, I didn't look up the button for in dash cassette, but it's in the manual, too)

 

In dash does not work will try random mode. Thank you

Also try 5 button

 

Just so there's no misunderstanding, here's the copy from the manual. If this doesn't work, either your unit is bad, or the disks are upside down or not being recognized (except for number 12)
