ABSTRACT:
A vehicle-mounted navigation apparatus includes a display control unit which reads road map data from a map data storage device used for storing a plurality of road map data concerning road maps with different reduced scales in accordance with a current position of the vehicle detected by a position detecting unit. The display control unit controls the read road map to be displayed on the screen of a display unit in accordance with a control signal from a touch panel unit and further reads a scale indication pattern from an indication pattern storage device used for storing a plurality of scale indication patterns showing the respective reduced scales corresponding to the stored road maps. The display control unit superimposes the selected scale indication pattern on the selected road map. Since a map with a desired reduction of scale with a desired scale indication pattern corresponding to the scale reduction of the map superimposed thereon can be displayed on the screen, the driver can readily obtain a map with a desired reduction of scale and a scale pattern corresponding to the reduction of scale on the screen, and thereby detection of the real distance can be readily and correctly performed, ensuring a smooth and safe cruising of the vehicle.
