Radio stopped working

All of a sudden, my radio won't turn on. I hope this isn't going to cause a lot of problems. What should I do first? Where's the fuse?

my truck just did this the other day along with interior lights and power mirros. There is a fuse in the cab fuse panel left side of dash when you open drivers door labeled I.O.D. fuse #12 on my truck. It has a black lock around it, dont know why, but that fuse is blown. I replaced fuse, lights come on, mirrors and radio work. hope this helps

It started working again, then went to static, the buttons couldn't turn it off, then when I parked it, it worked again, buttons lights everything...weird. My friend says it might be a loose wire rather then a fuse.

probably a loose ground wire.
