I have a 2001 SLK320 and the radio is not working at all. I checked the fuses and all good. Afterwards, the radio displayed "Code EJ". I entered my code and it worked. A few hours later, the radio stopped working and does not have a code error. I pulled the fuses out again and still no code error. I also reset the battery and still nothing. Any ideas?

 

I'm having the same exact problem,but with a 06 w211 E350. I have chkd all everything looks well, am I going to have to go the dealers(stealers) or does anyone know of some reputable radio repairers? please help, much n all appreciated.

 

I had the same problem, and decided to get a good after market radio due to repairing the MB radio was not cost effective.
