I searched and could not find a similiar issue. When I'm in googlemaps and have locked on to my location and have typed in a destination, the gps will follow me and show me on the map. However, when the arrow gets to the edge of the screen, it disappears and I have to move the map to keep it centered. In other words, it doesn't keep the map centered and I have to constantly keep moving the trackball or my finger over the window to follow me on the map. What am I doing wrong?
