Hey I had the same problem after I installed my pioneer. Keep in mind that there is also a fuse for the radio in the fuse box under the hood on the drivers side of the truck. My suggestion is before you replace any fuses make sure you pull the cd player and check that all the wires are hooked up correctly and either have soderless connectors on them or electrical tape so that none of them can ground out and blow another fuse. I hope this helps
