During a routine drive the main and part of the front screen went dark. The truck was functioning fine and the system went back to normal once I got home. Anyone know how to do a hard reset.
Did you try a screen reset? The manual explains both types of manual reset (you can also just lock the truck for 15-30 minutes for a "deep sleep").
The screen reset is probably best in these cases, where you press both of the outer buttons on the steering wheel at once for 15 seconds until the screens go completely blank. They'll then restart.
