horn, clock, and interior lights work? Radios have 2 power sources. Ignition and constant and the constant is often on the same circuit with the items mentioned above. Check those as well as the radio fuse. Also, don't just look at the fuse, best to check it with an ohmmeter and like heywier said, check for voltage at the fuse so you know if the problem is before the fuse or after it.
