Well I’m an idiot. I was fixing my power wire on the back, and while the wires were connected, but still exposed I sneezed and the wire must have hit a ground, and shorted out. The radio turned off, and won’t turn again. All the fuses on the car looked fine, and so did the fuse on the back of the head unit. Any ideas on something I missed, or a way it tell if the headunit went bad? 

Thanks

If you still have the unit...

There are a few fuses on the main circuit board you can check.

I would double check the wires on the car make sure it still have power. Then check the radio. Very rare it will be a internal fuse. But it does happen. Disassemble the radio as a last resort.
