Hi, welcome to Just Answer. My name is***** first thing to try is a hard reset on the electrical system. To do this you will need to disconnect both battery cables and connect a jumper wire between the two cables in order to discharge the memory in the control modules and reset the system. This will often get the radio functioning again. If this fails you will need to get the car connected to a Mercedes tester to check for faults in the COMAND system. The COMAND unit in the dash may require a software update or replacement.Let me know if you have any questions.
