3 times now on long trips over 2-3 hours I've had my 12" screen just go full black and not functional. The only was to have it function again seems to be shutting off the truck for at least 20-30 min. Frustrating to say the least and it's been looked at by the dealer 3 times while the truck was also in for other recalls. They say it seems fine and just did updating to see if it would fix it. Anyone else having this issue or do I have a real odd problem here? Appreciate the help.
