How do I reset my Mercedes radio?
To reset your Mercedes-Benz radio code, you will need to retrieve a corresponding radio code. To do this, either check your owner’s manual or contact an authorized Mercedes-Benz dealership with your VIN and proof of ownership. From there, enter the code into your radio, and it should successfully be reset.
Why is my radio not turning on?
The most likely reason for your radio’s sudden death is a blown fuse. All car radios have at least one fuse that protects it from power surges coming from somewhere else in the vehicle. The first thing you should do when your radio stops working is check its fuses and replace any that have blown.
