I have the same unit and have been playing cds that I have
burned for a couple of years and not had that problem. It does
occasionally start to 'skip' almost like a needle sliding across a
record, but restarting the tune cures that and it happens very seldom.
It also 'forgets' where it was occasionally when the car is stopped.
Normally it picks up where it was as soon as the car is started.
Sometimes it starts back at the beginning instead. No trouble with
directories. They seem to agree with it just fine. I can not imagine
how a burned cd could kill the player. Did it start to play the cd
when it was inserted or did it just lock up? Does the mechanism accept
a new cd? I would be tempted to remove the player and unplug it for a
time. It does have voltage even when the car is stopped since you can
play it without using the key. If the drive has gotten confused, it
will stay confused unless the power is removed. It might just reset
itself when power is again applied. Good luck.
