Ipod Classic that has worked fine on aux. cable in glove box of my 2011 treg for about 3 years. All of a sudden the ipod is stuck on one artist and won't shuffle to next song in line up. I've tried removing ipod and redoing playlist on computer in essence reindexing the playlist, I've created a whole new playlist including some of the same songs, I set my ipod on a different artist and try to make it play only the new artist and when I plug the ipod back into the aux. cable it reverts back to the old artist and will only play that artist. Anyone seen/had this problem? I'm at my wits end.
