My navigation out of no where has been restarting on its own meaning screen goes black and warning comes up again. I have had car since November and it only started happening last week and I have 6k on car. It will actually restart on its own twice and this has occurred 3 times so far.

Now not sure if I am dreaming this but if I shut the car off with NAV screen split with home screen I always remembered it staying that way even when I restarted car. Now however regardless of what I leave it when I restart car always shows full map. I am thinking did they push an update to NAV which is also causing the glitch in it restarting? I haven't brought it dealer since new so I know no one updated manually but I can swear home screen would stay split if I left it that way.

Regardless I was just seeing if anyone has been having issue with NAV restart while driving, I see it was occurring in IS forum but no fix. Also it is very cold but car is garaged and every time I been driving already for a bit, another thing maybe it's my iPhone because it always plugged in when it has occurred.

I've had the same random restarts with NAV starting at 3000 miles on my 2015 ES350. I was waiting for the 5k service to bring it up to the dealer. I don't know if they do over the air updates on this car, but if they do I would want some sort of notification at least so we know how to report the incidents better.

That's interesting, I've not experienced this myself but did have a co-worker tell me that his 2014 ES350 NAV was restarting as well. For him, he could get it to "reliably" fault and restart if he started the car and IMMEDIATELY shifted into reverse.

I'm not inclined to try to recreate his condition, but wonder if either of you get it to fault in the same manner?
