When the navigation button is operated, the control unit 16 returns the display of the display device 3 to the display of the guide image in which the display range is determined with reference to the current position in FIG. 5a.

  On the other hand, when the enlarge button is operated (step 408), the target area is changed to an area obtained by enlarging the original target area at a predetermined rate (step 424), and the changed target area is represented on the guide image. The target area graphic 502 is updated (step 426), and the process returns to step 406. When the reduction button is operated (step 410), the target area is changed to an area obtained by reducing the original target area at a predetermined rate (step 428), and the changed target area is represented on the guide image. The target area graphic 502 is updated (step 430), and the process returns to step 406.

As a result, for example, when the reduction button 503 is operated in the display state of FIG. 5c, the target area graphic 502 is reduced as shown in FIG. 5d.
Next, as shown in FIG. 5e, when the enter button 504 is operated (step 412), a display deletion / deletion selection window 510 is displayed on the display device 3 via the guide image generation unit 17 (step 412). 414) Selection of whether to delete the display of the user registration point or to delete the registration of the user registration point is accepted by the buttons 511 and 512 of the display deletion / deletion selection window 510 (steps 416 and 418). Then, if the selection to delete the display is accepted, the user registration point record having coordinates in the target area is extracted, the display flag of each extracted user registration point record is set to OFF (step 432), and all users are selected. The registration point mark is erased and the user registration point mark is redrawn based on the current user registration point data (step 422), and the process ends. On the other hand, when selection of deletion of registration is received, a user registration point record having coordinates in the target area is searched, and each searched user registration point record is deleted (step 420). Then, deletion of all user registration point marks and redrawing of the user registration point marks based on the current user registration point data are performed (step 422), and the process is terminated.

As a result, as shown in FIG. 5f, the display of the display device 3 is the one in which the user registration point mark 320 in the target area represented by the target area graphic 502 is deleted.

Only the display of the user registration spot mark 320 (the user registration spot mark of the flag figure in the figure) of the user registration spot of the genre designated by the user changes to a display that is erased.

  Alternatively, the determination button is operated while the target area graphic 502 is displayed as shown in FIG. 5c, and the display deletion / deletion selection window 510 is displayed as shown in FIG. 5e. If selection of display erasure is accepted, the display flag of the user location record of the user registration location having the coordinates drawn at the position overlapping the recommended route graphic 311 among the user registration locations in the target area is set to OFF. If the selection of deletion of registration is accepted in the display deletion / deletion selection window 510, the user registration point having coordinates drawn at the position overlapping with the recommended route graphic 311 among the user registration points in the target area. The user point record may be deleted. As a result, as shown in FIG. 6c, only the display of the user registration point mark 320 drawn at the position overlapping the recommended route graphic 311 among the user registration points in the target area is deleted. The display changes.

  Alternatively, the determination button is operated while the target area graphic 502 is displayed as shown in FIG. 5c, and the display deletion / deletion selection window 510 is displayed as shown in FIG. 5e. If the selection to delete the display is accepted, the display flag of the user location record of the user registration location having the coordinates drawn at the position overlapping the road figure in the guide image among the user registration locations in the target area is turned off. If the selection of deletion of registration is accepted in the display deletion / deletion selection window 510, the coordinates are drawn at a position overlapping with the road figure in the guide image among the user registration points in the target area. You may make it delete the user point record of a user registration point. As a result, as shown in FIG. 6d, the display of the display device 3 erases only the display of the user registration point mark 320 drawn at the position overlapping the road graphic in the guide image among the user registration points in the target area. The displayed display changes.

  Alternatively, the determination button is operated while the target area graphic 502 is displayed as shown in FIG. 5c, and the display deletion / deletion selection window 510 is displayed as shown in FIG. 5e. If the selection to delete the display is accepted, the display flag of the user location record of the user registration location having the coordinates drawn at the position overlapping the icon 304 among the user registration locations in the target area is set to OFF, If selection of deletion of registration is accepted in the display deletion / deletion selection window 510, a user point record of a user registration point having coordinates drawn at a position overlapping with the icon 304 among user registration points in the target area is displayed. It may be deleted. As a result, the display of the display device 3 is a display in which only the display of the user registration point mark 320 drawn at the position overlapping the icon 304 among the user registration points in the target area is deleted as shown in FIG. Change.

  Further, in the above embodiment, the target area is set around the position pointed by the cursor 330 by the user. For example, when the user performs a predetermined operation, the current area is set as the center. You may make it set a target area. For example, as shown in FIG. 6f, a semicircle on the current traveling direction side of a circle centered on the current position is set as the target area, and the display of the user registration point in the set target area is deleted or the registration is deleted. May be performed.

Hereinafter, a second embodiment of the present invention will be described.
In the second embodiment, instead of the user registration point mark erasing process in the first embodiment, the following user registration point mark erasing process is performed.
FIG. 7 shows the procedure of the user registration point mark erasing process according to the second embodiment.
