You will have to go to the dealer to get the reset code and instructions. It will be unique to your particular radio.
If your radio is locked and needs to be unlocked, it would require a security code versus a radio code.
The security codes for each radio are unique. There will be a card with the number in the original manual supplied with the vehicle when purchased new. There you will also find the procedure for unlocking the radio. If you do not have the original card containing the code you may go to your nearest Mercedes Benz dealer with I.d and proof of ownership of the vehicle and they will be able to get the code and tell you the procedure.

where is radio security code located for a 2005 ml 350 mercedes
What worked for me was to unplug the antenna in the back of the radio and then enter the security code. Once the security code is entered, you can plug the antenna connector back into the radio.
Never knew that there was a security code for the radio, just set the stations etc.
The radio unit will need the security code If you disconnect the battery from your vehicle. The radio will reset, thinking it was stolen out of the car, and will require the security code before it will work again.
