The MAPK displayed on TIOK includes portions that overlap with other sections.

This is to make it easier to see if the MAP is switched to another section's MAP.

When the CRT IOKMAP is displayed based on the image information recorded on the cassette tape and the vehicle starts running, as shown in Figure 3, the CRT IOKMAP is displayed as shown in Figure 3.
The traveling position of the vehicle is displayed as a traveling trajectory T on the CRTIO based on traveling position information obtained from detection signals from the vehicle speed sensor 38 and the direction sensor 40. Then, when the traveling position of the vehicle is displayed at the display MAP change point, a MAP switching calculation is performed based on the position information at this change point, and the calculation result is supplied to the cassette tape recorder 26 as a MAP switching command. Also, the change point of the displayed MAP is as shown in Figure 3 (line L1 at the four corners of 1 MAP).
It is set to %L2, L3, and L4.

By the way, the present invention is characterized in that a MAP suitable for the vehicle's progress is selected from among the MAPs adjacent to the displayed MAP, and it is possible to determine at which line change point the vehicle's traveling position is displayed and at the displayed position. The MAP is selected depending on the direction in which the vehicle is traveling.

For example, as shown in FIG.
