I just bought a prime condition 1994 E320 with the premium sound system. Today the radio went bonkers. It comes on when you turn on the engine, but step on the gas and it goes off. Stop at a light and it goes back on, accelerate and it goes off. I do not detect any other equipment malfunctioning. Needless to say as a music lover I find this to be very annoying. Doers anyone have any suggestions on what may be happening? I am thinking of disconnecting the battery and then reprogramming the radio when I reconnect using the code.
