This is what it says when truck is started. The CD player will not play from where it stoped playing when truck is started again. Any Ideas why? It plays cds fine, I only see the err thing when I start the truck up.

The truck is wifes 02 Tahoe with stock cd player.

Mine started doing this... Right before it took a retro-dump and wouldn't play any CDs at all. Try a cleaning CD first, then prepare yourself to get a new one.
