Electronic navigator for automotive vehicles.

摘要

An automotive navigator using a microcomputer displays a car position by a cursor on a road map displayed on a CRT screen (6). The navigator uses a cassette tape (3a) which stores a plurality of road map data and several kinds of reduced map data and expanded map data. It also uses a group of manual switches (7, 8) including a switch for changing the displayed area, a switch for selecting an expanded map or reduced map and a switch for moving the cursor position. Necessary data are displayed on the screen by the state of each switch. A region corresponding to the cursor position is displayed by the expanded map.
