ABSTRACT:
The invention provides a method of displaying maps for a vehicle navigation unit that displays a wide area map and an expanded map simultaneously on the display screen, and scrolls the detailed map on a cursor screen synchronously with a cursor movement on the wide area map, thereby facilitating the driver's comprehension of the vehicle's position on the map. The method to achieve the foregoing object comprises: dividing a display screen into a main screen and a cursor screen; when the two-screen map display is requested, displaying a wide area map on the main screen and at the same time displaying on the main screen a cursor indicating a specific area on the wide area map; displaying a detailed map on the cursor screen of an area indicated by the cursor; moving the cursor on the wide area map on the main screen in accordance with the travel of the vehicle, and scrolling the detailed map on the cursor screen in accordance with the movement of the cursor; and, when the cursor reaches a specific position on the main screen, displaying a wide area map adjoining the foregoing wide area map on the main screen and displaying the cursor at a setting position on the main screen.
