Welcome to Benzforum. I think Lynn is correct, the dealer should be able to provide the code, based on the VIN number. If the Radio has been replaced, you will need to pull the Radio and provide the serial number to your dealer. Hopefully, they can provide the correct code based on the VIN.
Need a little more help on unlocking the radio 1999 C280
Ok I got the number from a local dealer and then put in the number using the key pad to the right. It then said ok but did nothing except flash on the first number again is there anything else I need to do or any other buttons I need to push. Thanks for the help
