Hi, I have a 1997 Mercedes E420 and the radio just died today while doing my usual driving. It won’t turn back on once I restart the car and shows no signs of “life.” I want to listen to the radio in my car, but am really curious as to what happened and is this a common occurrence in this year and model? I should mention that I am the 3rd owner and have owned the car for a little over 6 months now. The car has over 118K miles on it too. I hope to get some help on this one. Thanks, Janna
In addition to my previous comment, the radio appears to be the original one the factory put in. Thanks! Janna
