The black screen has been with remote start and without.

I was sitting in the driver seat this morning with key fob in-dash starting the truck, and it was black, wonderful when it's 5 degrees outside.

I pulled the radio fuse under the hood, and it rebooted the radio, then everything was back to normal.

For the 100$ NAV, I saw it when I was looking into jailbreaking my radio.
