2017 Q60 red sport 400. This started tonight. After driving car, then parking, the nav screen ( top half of center console) went black after I put car into reverse. No rear camera view, no map, no nothing). Had to turn off car and restart to get it to work. Happened again an hour later when i got home after driving for about 15 minutes. Pulled into garage, put it in Park, then put it in Reverse to see what happened. Same thing - screen went black. It appears as though audio functions still worked. I was able to get voice commands with steering wheel controls. But, screen stayed black til i restarted. Heard this was a problem with older infinitis. Anyone else see this?
