It employs a cassette tape that stores various road map data, including reduced and expanded map data. The system features a group of manual switches that allow users to change the displayed area, select between expanded or reduced maps, and move the cursor position. The necessary data is displayed on the screen based on the state of each switch, providing an expanded map of the region corresponding to the cursor position.

Another significant patent is a navigation system designed for use with automobiles, which includes a reading unit. This system displays a road map based on information retrieved from a cassette tape, along with the current location of the vehicle. A cassette tape distinguishing circuit is integrated into the cassette tape player, which retrieves road map information from a specific cassette. A switching circuit responds to the distinguishing circuit, ensuring that the output data is processed to display the appropriate map only when a cassette containing road map information is loaded. If a standard audio cassette is loaded instead, the audio signal is transmitted to an amplifier for sound reproduction. This design allows a single cassette player to function as both a navigation system and a sound reproduction system.
