Radio/navigation screen issue and mirror question

I’m having an issue where my navigation/radio screen won’t always turn on even though the system is on and radio is playing through speakers. I only see the issue occasionally and only after I put the truck in reverse (backup camera displays with no problem), backup, and then shift into drive (screen goes blank). As soon as I push the home button the screen pops on.

I had the dealership check it out at my last service appt and they said they did a software update which should have fixed it. The problem seemed to have gone away but after a few weeks it is showing up again.

Has anybody else had this issue? This is on a 2015 SR5.


Totally unrelated... does anybody know if it is possible to upgrade the OEM mirrors on the SR5 with power folding mirrors?

 

Bumping this once...hoping somebody might have some idea what’s going on with the display.
