Question radio problems

I have a 2002 ml 320. i recently changed the battery on my truck and when i turned it back on I got a message on my screen of operation system (navigation system-radio) asking to enter security code. Does anybody know if there's an universal code to unlock this problem?????

Contact a mercedes dealership with the VIN and proof of ownership. They can give you the code.
