Abstract
In a vehicle-mounted navigator, a control unit reads map data from a memory unit and displays a corresponding road map on a CRT display unit. In response to signals from a distance sensor and a direction sensor, the present position in relation to the running of the automotive vehicle is computed to display by superimposition the present position on the road map display of the display unit. When the computed present position has reached to a predetermined portion of an adjacent area, the map data of the road map adjacent to the road map on display is read from the memory unit and a corresponding road map is displayed on the display unit manually or automatically. In accordance with this updated display, the present position display is moved to a corresponding position on the updated road map display.
