radio code? on 1997 Mercedes-Benz C280

My brother changed the battery in the car and now the radio is locked. What is the radio code?

You should have got the code when the vehicle was first purchased it may still be in with the owner's manual and literature that came with the car. The dealer may be able to give you the code if you show proof of ownership and the VIN number of the car. Some car manufacturers you have to take the radio out of the car to get the radio number itself.
