  In the example of the display screen shown in FIG. 5, a message “Do you want to set the destination?” Is also displayed. When the user selects “Yes”, this Italian restaurant “XXXXX” is the target. A route search is performed by setting as a ground.

  By performing such control, the user can visit an unvisited facility included in a category he / she likes as a destination by a simple operation and visit based on route guidance.

  Next, the case where the unvisited facility guide unit 24 guides the user to unvisited facilities existing within a predetermined distance from the searched route when the route search is performed will be described.

  For example, when a route search is performed by the route search / guidance unit 21 because the user has set a destination, a display as shown in FIG. 6 is performed.

  In the example of the display screen shown in FIG. 6, a guidance display 52 indicating that there is a facility that has never been visited is displayed within a predetermined distance, for example, 1 km from the searched guidance route. An Italian restaurant called “XXX” is shown.

  In the example of the display screen shown in FIG. 6, a message “Do you want to set as a stopover?” Is also displayed. When the user selects “Yes”, this Italian restaurant “○○○○” It is set as the ground and the guide route is re-searched.

  When such a control is performed, if there is an unvisited facility included in the category that the user prefers near the searched guide route, the user can select a guide route that is based on the unvisited facility, It can be set easily.

  Finally, a case will be described in which the unvisited facility guide unit 24 guides the user to unvisited facilities existing within a predetermined distance from the guide route during route guidance.

  For example, the display as shown in FIG. 7 is performed while the user is performing route guidance by the route search / guidance unit 21.

  In the example of the display screen shown in FIG. 7, when the user moves on the guide route as it is, a guide display 53 indicating that there is a facility that has not been visited is displayed after a predetermined time, for example, 30 minutes. An Italian restaurant called “XXX” is shown as a facility.

  In the example of the display screen shown in FIG. 7, the message “Are you going through this facility?” Is also displayed. When the user selects “Yes”, this Italian restaurant “○○○○” The guidance route is re-searched.

  When such a control is performed, when the user moves around the searched guide route and passes near an unvisited facility included in the category he / she likes, the visit is made without overlooking the unvisited facility. It becomes possible to do.

  It should be noted that whether or not the unvisited facility guidance unit 24 guides an unvisited facility that has not yet been visited by the user among the facilities included in the category determined to be the category preferred by the user. You may enable it to switch by operation. Furthermore, the category determined to be the category preferred by the user may be changed by the operation of the operation unit 16 so that the category is not preferred by the user.
