Please let us know what you find. We are interested to see what it is.

I wasn't very descriptive in my question. The radio is on constantly but the radio display reads diagnosis and does not function., also, the dash cluster reads diagnosis as well. I've tried the fuses and they are all fine. Called Mercedes dealership and they said it sounds like it could be a module failure. I'm not very familiar with car parts besides the basics. would a failed module do that?

Could it possibly be my radio anti theft is on and locked me out of the radio?

I fixed it! It was the radio anti theft lock. I found the steps on a Mercedes support page and it worked. Thank you for the help!

Thanks for the update. I am sure that info will help others as I am sure you are not the only one that has had that issue.

Please come back to 2CarPros in the future if you need more help. Thanks

Hey, do you have the link of the support group or can you tell me how you got rid of the “diagnosis” screen?

Can you tell me what support page or provide the link? I have the same problem?
