This happened twice today in my S85 running firmware version 5.9. Was driving on the freeway with cruise on at 71mph, playing music from my iPhone via Bluetooth, navigation route set and map display on bottom half of screen with top half of screen showing rear view camera image. Suddenly center display went dark except for rear camera image (first photo shown below) for a few seconds then entire display went dark except for Tesla logo in center of display for another few seconds (second photo shown below) then center display went back to the way it was before: rear view camera image in top half and navigation map in lower half. It was as if the center display was spontaneously rebooting. The driver display never changed, it behaved normally and the Navigon nav continued without interruption. Had the odometer display running on the drivers display.
I will have to contact my local Service Center about this next week.
(note: the light colored shape in the lower part of the display is a reflection)
