My CD player doesn't work. It says "Error 4" and won't accept a disc, and won't eject the discs in it. It has not been fixed and the dealer blames it on homemade CDs.
error 4 message, can not eject disc or play.........
GPS out of date. No free software upgrades known.
cd changer has been taken out for repair 3 times, error message 3 or 4 has returned in a very short time obviously every time. What kind of inferior product is in these cars?! This appears to be a big issue.
