I download the version onto a USB drive and when I plug it in it will not go to the green screen for updating. All it does is says rebooting system then it turns back on and says downloading update and reboots. It does this probably 4 or 5 cycles and then the system shuts off until I turn the truck off and back on.

Your update should not do this. There is something wrong with the update method or something.

I guess what I am wanting to know is if there is a way to check and how to check the system with forscan to see if my GPS is messed up or if there is a setting in the system to check?

There are several threads here that outline this issue. This is one of the more comprehensive.
