I had it happen again last week. I was not using VIM at all. I entered GPS to go to my location, and in the exact same spot as last time, the GPS froze. I was going through a toll booth and when the scanner read my EZPass it locked up. When I went through the next EZPass toll an hour later it jumped to that location, and when I went through a 3rd EZPass another 10 minutes later it jumped to that one. I even pulled over, shut the truck off, opened the door to shut the screen off, restarted, and the GPS was still locked at the toll booth. Only 20-30 mins later did it finally unfreeze location. It would just show the icon pointing the direction I was going, but not moving anywhere. I didn't use VIM or any NAV-TV feature.
It's definitely related though, I've been through those toll booths probably 100 times at least since I've had my Raptor, and never once did it ever lock up. Now both times I've been through it with NAV-TV, it has.
