My fiancées father had a D1 laying around for a couple of years, so I installed it on her 2004 CRV. Everything works, except I'm having an issue with the navigation map. When I start the car, it knows my current location, but when I drive the arrow does not track on the street I'm driving on. It just stays at my original location, and when I turn the arrow will just turn on the same spot. Any clues what might be the issue?
