I have the factory navigation in my car and it works fine. I don't remember having to adjust any settings or anything when I picked it up and I doubt the guys in Washington adjusted it prior to putting it on the boat.
Hit NAV and then hit MENU and see if there are any settings that might have to be punched in. There might be something under SETTINGS in the main menu as well. Just a thought.
