Hello, I have just bought an old 2003 e270 and I can`t figure out what to do with my radio. I have been looking all over the internet to get a code for the Audio 20 but it seems like there is none,at least that is what everyone says. Maybe one of you can help me out.Thanks

there is no radio code for that radio.

need to do a hard reset and see what it does. if it still comes up with this than possible software update may fix issue. if not than you need a new radio. it may not be a bad idea to take it somewhere that is familiar with your car and has MB diag capabilities .
