Sound as if there is an internal problem with the system. Will the CD eject when commanded? If not, try to remove it manually with a pair of tweezers or something of the sort to see if it will come back on line.

If nothing gets better, suspect an internal unit issue

Very common problem - especially if you did not buy the car new. The dealer can override the code in your radio and reprogram it with a PIN code that you can remember in case it happens again. (It will happen again anytime the battery runs dead or is disconnected) Make sure you take your picture ID and proof of registration with you to the dealer because they are not "supposed" to unlock a radio for anyone except the registered owner of the car. This is to prevent someone from stealing your radio and using it in another car.

try to call the vendor on the radio. most of the time they will have a master reset code
