my boss has a 99 ml320 and the radio won't shut off. I think it's in the ignition switch, but since i don't know mercedes systems, i dont know where to start
Hi, my name isXXXXX you mean that the radio will not turn off when you remove the key from the ignition? Are you able to turn the radio off using the switch on the radio?

Ok, if you remove fuse 10 in the fuse box under the hood will the radio turn off?
