Abstract

A vehicle-mounted device 10 includes reception means 60 for receiving a telephone number and positional information about a first point location from a portable device 30, storage means 70 for storing telephone numbers and positional information about multiple second point locations, first comparison means 62a for comparing the telephone number of the first point location with the telephone numbers of the multiple second point locations, second comparison means 62b for comparing the positional information about the first point location with the positional information about the multiple second point locations, display means 63 for displaying a point of interest on a map on the basis of comparison results of the first and second comparison means by using either the positional information about the first point location or the positional information about one of the multiple second point locations corresponding to the first point location. A navigation system 100 includes the above vehicle-mounted device 10 and the portable device 30.

Claims

1. A vehicle-mounted device comprising:

a reception part configured to receive a telephone number and positional information about a first point location from a portable device;

a storage configured to store telephone numbers and positional information about multiple second point locations;

a first comparison configured to compare the telephone number of the first point location with the telephone numbers of the multiple second point locations;

a second comparison configured to compare the positional information about the first point location with the positional information about the multiple second point locations;

a display part configured to display a point location on a map on the basis of comparison results of the first and second comparison part by using either the positional information about the first point location or the positional information about one of the multiple second point locations corresponding to the first point location;

wherein;

the first comparison part determines whether the telephone number of the first point location coincides with any of the telephone numbers of the multiple second point locations, and the second comparison part calculates distances between the first point location and the multiple second point locations; and

the display part displays the point location on the map by using the positional information stored in the storage part in a case where the telephone number of the first point location coincides with any of the telephone numbers of the multiple second point locations, and displays the point location on the map by using the positional information received from the portable device in another case.

4. The vehicle-mounted device according to claim 1, wherein the display part displays an alert message to a user in a case where the point location is displayed on the map by using the positional information received from the portable device.

5. The vehicle-mounted device according to claim 1, wherein:

the reception part receives, from the portable device, identification information a first map database in which the first point location is included;

the storing part stores identification information about second map database in which the multiple second point locations; and

the display part displays the point location on the map by always using the positional information received from the portable device in a case where the identification information about the first map database coincides with the identification information about the second map database.

2. (canceled)

3. (canceled)

6. A navigation system comprising:

a portable device having a sending part configured to receive a telephone number and positional information of a first point location to a vehicle-mounted device; and

the vehicle-mounted device including;

a reception part configured to receive the telephone number and positional information about the first point location from a portable device;

a storage part configured to store telephone numbers and positional information about multiple second point locations;

a first comparison part configured to compare the telephone number of the first point location with the telephone numbers of the multiple second point locations;

a second comparison configured to compare the positional information about the first point location with the positional information about the multiple second point locations;

a display configured to display a point of interest on a map on the basis of comparison results of the first and a second comparison configured to use either the positional information about the first point location or the positional information about one of the multiple second point locations corresponding to the first point location;

wherein;

the first comparison part determines whether the telephone number of the first point location coincides with any of the telephone numbers of the multiple second point locations, and the second comparison part calculates distances between the first point location and the multiple second point locations; and

the display part displays the point location on the map by using the positional information stored in the storage part in a case where the telephone number of the first point location coincides with any of the telephone numbers of the multiple second point locations, and displays the point location on the map by using the positional information received from the portable device in another case.

7. The navigation system according to claim 6, wherein the portable device includes a mobile communication part configured to acquire information about the first point location.

8. A control method for a navigation system including a portable device and a vehicle-mounted device, comprising:

sending a telephone number and positional information of a first point location to a vehicle-mounted device;

comparing the telephone number of the first point location with telephone numbers of multiple second point locations stored in the vehicle-mounted device;

comparing the positional information about the first point location with the positional information about the multiple second point locations;

displaying a point of interest on a map on the basis of results of comparisons about the telephone number and the positional information by using either the positional information about the first point location or the positional information about one of the multiple second point locations corresponding to the first point location;

determining whether the telephone number of the first point location coincides with any of the telephone numbers of the multiple second point locations;

calculating distances between the first point location and the multiple second point locations;

displaying the point location on the map by using the positional information stored in the storage part in a case where the telephone number of the first point location coincides with any of the telephone numbers of the multiple second point locations; and

displaying the point location on the map by using the positional information received from the portable device in another case.
