Anyone having the same issue? All aircraft with the Garmin glass cockpits remain DARK, even if starting ready for take-off on runway? Tried turning on and off avionics switches, to no avail. Never had this before…

Working Title G1000 and G3000 both work great. The G3X clashes with them. THe current version causes nav issues. Older versions cause the screens to go black in other planes.
