The data is output to the main controller 1. The vehicle position processing device 2 also outputs vehicle speed data obtained from the autonomous navigation sensor 2a to the main controller 1.

The map database 3 is composed of a CD-ROM or the like, and stores a plurality of types of map data of different scales and data such as regulations for the same area. The recording medium reading device 4 reads map data of an area designated by the main controller 1 from the map database 3 and supplies the map data to the main controller 1. The main memory 5 is backed up by a battery and stores a plurality of types of map data of different scales supplied from the main controller 1.

The input device 6 includes a touch panel shown in FIG. 2 and a remote controller and keys shown in FIG. 4, and performs initial settings such as a current position and a destination before or during use of the device, activates the device, and scales a map screen. To change.

The video processing device 7 includes a graphic controller 7a, a video RAM 7b, and a display device 7c. The graphic controller 7a develops and stores the map screen data calculated by the main controller 1 from the map data and the recommended route data calculated by the main controller 1 in the video RAM 7b, and stores the map screen data in the RAM 7b on a display device 7c such as an LCD.
