I am not sure if any one has had this problem but if so I could really use some help. I have a 2004 SLK 230 Kompressor. The radio works however no sound comes out of it. I am hoping there is a way to reset it or that a wire is loose that I can fix. I am moving to Colorado (a 1,000 mile drive from me), and I can't not have the radio for 16 hours. Please anything helps and if you can give advice on where to look, that would be great. Thanks!!!
