I have a 2019 F150 Lariat with the 8" touchscreen. Sometimes with the screen on Home I shutdown the truck. The next startup puts up the Audio Screen or another screen. Is this normal? Or should the screen remain on the last selected?

 

Mine always stays on last screen. Is everything updated? If it happens a lot, I would do a reset through the settings.

 

Normally it sticks to the screen that was active when ignition was last shut off.

However, if you have used FOREScan to enable the heated seat controls to the home screen, the home screen will always be first visible when turned on.

If you did not purchase new -confirm there are no heated/cooled seat icons displayed on the home screen...meaning the previous owner didn't enable that.

 

Purchased new, no Forescan changes and there are no heated/cooled seat icons displayed. Will have to try the master reset.

 

Sounds more like a timeout condition (BCM not telling the APIM to go to sleep).
Sync will skip its boot animation if the truck hasn't been off long enough or if you haven't gotten out with the ignition off, closed and locked all the doors.
Just hold power and seek forward on the dash for 10 second to reboot Sync if you think the system is frozen. I doubt a master reset will change anything other than erase your EQ settings.

 

This happens at different times between shutdown and startup. In all the cases, the ignition was off, all the doors were closed and locked. I don't think the system is frozen since I can use the touchscreen to change the displays and control the radio, navigation and the heated steering wheel. I'll try the power and seek forward to see it that works.
