I just posted a solution for this problem. It comes straight from the radio manual. The dealer should have told you this. If you want him to do it he'll charge money for his time. IF YOU LOST YOUR CODE. THE DEALER CAN HELP YOU OR IF YOU HAVE YOUR 4 DIGIT CODE:

Hi, Joe here to help. The cd changer is at fault. You need to replace the changer. The system is on a fiber optic loop which cuts out the sound if can not complete that loop.

You will need to take the car to a dealership to have the service department unlock the radio for you. They have a special code to unlock the radio and then you are required to change the code to one that you will remember. An appointment should not be needed because this takes about 5 minutes. I do not remember the code, sorry.
