Further, when the display instruction of the unnecessary list is input, only the facilities having the importance of "unnecessary" are extracted and displayed as the unnecessary facility list. By doing so, the user can easily grasp unnecessary facilities. It should be noted that such a facility list may be displayed, for example, in ascending order of the current position.

In the present embodiment, the facility data is described as an example of facility data that can be registered by the user. However, for example, the facility data storage unit 25a of the map data input device 25 can be used.
3A may be stored in the user registration memory 29a as facility data in association with the facility unique code number and the facility name and telephone number shown in the upper part of FIG. Then, when the screen of FIG. 3A is displayed, when the facility data corresponding to the facility unique code number of the facility data to be displayed is present in the user registration memory 29a, the facility of the map data input device 25 is displayed. Instead of displaying the facility data stored in the data storage unit 25a, the facility name and telephone number existing in the user registration memory 29a are displayed.
By doing so, when the facility data recorded on the recording medium read by the map data input device 25 is different from the actual facility data, the user can input and store the correct contents, and in the subsequent processing. Various processes can be performed using the correct facility data input by the user.

The facility mark shown in FIG. 3B may be registered by the user in the same manner. This allows the user to change the type of facility mark. In this case, the facility mark may be stored in association with the facility unique code number, or may be stored in association with the facility type. The facility mark may be image data of the facility mark, or information such as a mark number for identifying the image data.

In the present embodiment, as shown in FIG. 3B, the facility registered as "important" is displayed with a thick frame, but it may be displayed conspicuously. You may change and display a color. For example, a prominent color, a color that draws the user's attention, or the like may be used. Further, although the facility registered as "unnecessary" is displayed with a thin frame, it may be displayed in a light color or the like so as not to be conspicuous.
