Radio problems
 

I have a 2004 ford f350 with 6.0.
My radio recently started increasing and decreasing while driving down the road. Then it quit altogether. The faceplate shows all the features volume up and down on and off stations both am and fm but no sound of any kind, nothing no static or anything.

Has anyone had this happen? I would like to keep it original. It came in the truck its a 6 track cd. Has been good up to this.

Thanks
Alton
