And my unit is stuck on the 0-60 finished test screen. I shut the truck down but the unit stays on.
When the Gryphon screen stays lit after shutdown, it's generally a sign of a failing battery. Please disconnect your Gryphon from the OBDII port (the lit screen will rapidly deplete a weak battery) and have your battery load tested.

When you reconnect, make sure the ignition is ON, before you plug the Gryphon in so that it can boot properly.
