Out today when all of a sudden I lost my GPS. This is on a route that I travel regularly. Ended up having to use google maps on android auto. Came back the same way, after a couple of hours, and everything was fine.
Ford Dealer said there was nothing wrong with mine, but it always seems to throw a wobbler when I need it. Next time it happens, carry out a soft reboot (Hold forward and Power button until unit reboots). This fixes it, until the next time.
