The map data may be read from a recording medium other than the data storage device 19, such as a DVD-ROM or CD-ROM.

  The destination-recommended facility genre correspondence table shows the correspondence relationship between the genre of the facility set as the destination and the genre of the facility proposed by the navigation device 1 after arrival at the destination (hereinafter referred to as recommended facility). It is the recorded correspondence table. An example of the destination-recommended facility genre correspondence table will be described with reference to FIG. The genre of the recommended facility in the destination-recommended facility genre correspondence table is the genre of the facility that proposes to go after the user arrives at the destination and completes the predetermined requirements.

  For example, if a public bath is set at the destination, it is expected that the body will be drained by sweating with the public bath, and the ramen will be more delicious, so a ramen shop is set as the recommended facility genre. In addition, when a gym is set as the destination, it is expected that sweating will occur due to exercise, so in order to sweat, a public bath is set as the genre of the recommended facility. Furthermore, when a movie theater is set as the destination, it is very fun to talk with the other party who watched the movie together, so the coffee shop is set as the genre of the recommended facility. In addition, assuming the user's situation after completing the predetermined requirements at the destination, the genre of the facility appropriate for the assumed situation is set as the genre of the recommended facility. In the destination-recommended facility genre correspondence table shown in FIG. 2, there is one corresponding recommended facility genre for each of the facility genres set as the destination.

  The display monitor 16 displays various information such as a map near the current location based on various information such as map data. The speaker 17 outputs sound for instructing the user to perform various input operations and for guiding the route. The input device 18 has operation keys for the user to set various commands and input search conditions, and is realized by a button switch on the operation panel, a hard switch around the panel, or the like.

  In step S105, it is determined whether or not the ignition switch of the vehicle is turned on. When the ignition switch of the vehicle is turned on, an affirmative determination is made in step S105, and the process proceeds to step S106. If the ignition switch of the vehicle is not turned on, step S105 is repeated. In step S106, the genre of the recommended facility corresponding to the genre of the destination is searched with reference to the destination-recommended facility genre correspondence table, and the genre of the searched facility is determined as the genre of the peripheral search. In step S107, the vicinity of the facility around the destination is searched using the genre determined in step S106 as the search condition.

  In step S108, the facility searched in step S107 is proposed to the user as a recommended facility. For example, a list of recommended facilities, an icon on a map, or aloud is suggested to the user. In step S109, it is determined whether the user has selected a recommended facility. When a plurality of recommended facilities are searched, the user selects one recommended facility from the plurality of searched recommended facilities. When the user selects a recommended facility, an affirmative determination is made in step S109, and the process proceeds to step S110. If the user does not select a recommended facility, a negative determination is made in step S109, and the facility proposal process ends. In step S110, route guidance to a recommended facility is performed.
