Location of a Blown head unit fuse

Where abouts would it be? I've looked inside my manuals that came with the truck rather thoroughly, and have found nothing, there's something called the "head" on the fuse box inside the cab... i'm so close to just checking every fuse as my head unit wont turn on.

Hi, I was just wondering if your radio is stock or aftermarket. An aftermarket head unit has a fuse located directly on the rear of the head unit.

There are 3 possible fuses that are part of a factory radio. One is the ACC fuse located in the dash panel fuse block. Then you have "radio 1" fuse and "radio 2" fuse located in the under-hood fuse block. (Left front of engine compartment)

No blown fuses..

Well i've checked all of them and some more fuses, and none are blown. ALso the cigarete adapter is also not working, and apaprently one needs the other to work.. and more ideas as to why it isn't working would be much appreciated!

OK. Just going back through this, you mentioned the head unit wont turn on, and you have included that the cigarette lighter/power port is inop as well? Lets get into a bit more detail then. Do you have the built in amplifier option, or not? That information may help a little. Also, do you have ANY display at all? (Clock, illumination, etc) on the radio?

Also, when you checked the fuse, did you just look at it, or did you actually use a test light to verify it had power on both sides of the fuse? The ACC fuse supplies power to the radio, as well as a relay that sends power to the cig lighter. That is why I asked.

I'm away from my truck in Florida, but will be back soon. If I didn't blow a fuse what's up next on the check list?
