Check your owner's manual - otherwise you will have to get the radio code from Mercedes. They are unique to each vehicle.

you can go to a Mercedes dealership to have this done if you do not have the code or you can go to this website to get the code with instructions how to set the code in your radio
the cost of this is a fraction of what the dealership charges you

here is the website to get your code

I found this page but I haven't tried it to know if it's right for your radio code or how much it costs.

The main dealer will supply the code usually for a small charge.
Have a look on line first though because some are offered freely .
You will need the model year and chassis number.

hi,you may ask your dealer to coordinate mercedes benz center,to provide radio code,ty

go to dealer need radio code or try 1234
