My Radio crapped out today

[ohnodarlin]

Hey all. When I first started my car today and went to change the station, my radio went on the fritz. First the screen went blank and I tried to press the volumn knob to turn the radio off but that didn't work. So I turned the car off and started it again but no dice. The volumn can go up and down but I can't change the station or the function from AM to anything else. Everything else is running as usual. As I was driving, the screen was flashing all sorts of weird symbols, like it was scrolling through all of the functions and options available. After about 20 minute the screen went perfectly normal and I tried to change the channel and the whole thing went blank. I thought that if it were a fuse, something else wouldn't be working but then again I could be wrong. HELP!
