Did the most recent update, still same issue. Called humminbird and they said I need to send it in for repairs. Returned to Cabelas and came home with the Garmin 73SV!
So I do that and it goes into the screen that’s says shutting down. Then it just sits in the shutting down screen endlessly. The screen doesn’t go back to back menu or on screen. It’s stays on “shutting down” screen.
