I have a 2021 Subaru Legacy Touring and have the same problem. The whole screen blanks out for a minute or 2 and when it comes back the sound for the navigation does not work until the car is restarted. I have taken it to the dealer but of course the problem did not happen for them.Just got back from a trip where the entire console blacked out and restarted four or five times along the way, maddingly just as I was in the city and needed nav guidance. Happened both with built-in nav on and using maps and music apps in CarPlay. It had done this once or twice before in the six months or so I've had the car but my dealer couldn't replicate and therefore said they couldn't fix. Anyone have similar issues and, if so, how did you get this resolved? I checked for software/map updates maybe a week ago and had the latest at that time. Thanks in advance.
