The screen on my 2021 37 periodically does not turn on with the ignition, or sometimes it takes a few minutes to come on. Thus far when it does not turn on, I turn the vehicle off and restart it, and that seems to work. Any opinions?

Master reset and check for available updates.
It should update automatically, correct? I had problems with a SYNC 3, updated it with Ford thumb drive after a master reset, and it crashed. It was at the dealer for three weeks….I’m a bit Gun shy

Mine does this sometimes but only because it’s as hot as the surface of the sun so I just ignore it as long as it eventually comes up.

This just happened to me this morning. Turning the truck off and back on didn’t work. Drove a few minutes down the road to the gas station to fill up ($111.00 ), when I started the truck, everything was working just fine. Was running errands w/ the wife, and had no issues the rest of the day with multiple store stops.

You probably have LineX on yours :)
LineX on the hood, I would do it all over again!! I have a 2019 with hood and doors with Line X. Tons of positive comments on both….not that I care. Nothing wrong with not following the herd!
