When I backed my 2015 Prius out of the garage, the display. seems to be OK. As I drove, the display was alternated between the navigation screen and the attached image every couple of seconds. I did not start the navigation app and I have nothing plug into the USB port. It didn't do anything when I press the "confirm" button. After I shut off the car and restart it after about 15 minutes, the display is working properly without this strange message. Is this one of those glitches that I don't need to worry about?
Maybe a dirty USB port causing a partial short circuit? I'd take a look in there with a flashlight to see if it's full of lint & dust.
