If the fuses are all good, you need to purchase a new radio.

I hate when that happens!
Every time that happened to me I had to buy a new fuse or a new radio.
If you have to buy a new radio--
If you buy a stereo from Best Buy for over $100. They will install it for free.

Well, "sometimes" there are fuses inside the radio too. I'd check there too first.

O yea by the way my cig lighter quit working to

Then something must of shorted out.
