Today i was changing some cd's and the radio locked up on me. I can't turn it off or on. Its still on the same station (pop, it's killing me) and its at the same voulume. I pulled the radio fuse and that didn't do a thing. Any advice for me please? When i take the keys out its still on, the led is, but its not playing music. Only when its on the #2. acces. posistion on the ignition.
