Both of the auxiliary power jacks (cigarette lighters) AND the USB Port are out. I had a radar detector plugged in the front jack and accidentally smashed it when loading some things into the passenger side. When I pulled out the broken plastic, a small metal piece fell in and made contact in the bottom. It made a small spark! Now, front and rear are dead. The USB is a different issue I suspect.

 

You blew the fuse. Replace it.

As for the USB, I'm not sure if its on the same circuit.
