A display screen superimposed with the current position information of the user of the navigation device 100 acquired every predetermined cycle (for example, every second) by 202p, and a guide route included in the guide data stored in the guide database 206g Route guidance information composed of voice guidance data associated with the traveling direction at the upper branch point is generated (step SD-14). Here, the route guidance information generation unit 202q may further generate route guidance information including a display screen of display guidance data such as TBT included in the guidance data.

  Then, the route guidance control unit 202r of the navigation server 200 transmits the route guidance information generated by the route guidance information generation unit 202q to the navigation device 100, whereby the map including the guidance route on the display unit 114 of the navigation device 100. Route guidance information including a display screen on which the guidance route data and the current position information of the user of the navigation device 100 are superimposed is displayed on the map data, and the route information on the guidance route is displayed via the voice output unit 118 of the navigation device 100. Route guidance information consisting of voice guidance data associated with the direction of travel at the branch point is output (step SD-15). Here, the route guidance control unit 202r further transmits the route guidance information generated by the route guidance information generation unit 202q to the navigation device 100, so that the display guidance data such as TBT included in the guidance data is displayed from the display screen. The route guidance information may be displayed.

  Then, the update determination unit 202i of the navigation server 200 updates the facility information corresponding to the facility ID stored in the facility information database 206a based on the facility ID of the searched facility information stored in the search facility information database 206c. Is referenced at a predetermined cycle (for example, 10 days) (step SD-16).

  Then, the update determination unit 202i of the navigation server 200 updates the selected facility information stored in the selected facility information database 206b based on the update date and time referenced in step SD-16. It is determined whether or not the facility information has been updated by the input of a review comment or a review evaluation by the review reviewer corresponding to the included review reviewer ID (step SD-17).

  Then, the update determination unit 202i of the navigation server 200 has the facility information corresponding to the facility ID stored in the facility information database 206a based on the facility ID included in the searched facility information stored in the searched facility information database 206c. The facility information corresponding to the facility ID stored in the facility information database 206a is selected based on the facility ID that has not been updated or is included in the searched facility information stored in the searched facility information database 206c. If it is determined that it has not been updated by input of a review comment or review review by the review reviewer corresponding to the review reviewer ID included in the selected facility information stored in 206b (step SD-17: No), the process is performed. Move to SD-16.

  Then, the update information generation unit 202s of the navigation server 200 uses the facility ID stored in the facility information database 206a based on the facility ID included in the search facility information stored in the search facility information database 206c by the update determination unit 202i. Or the facility information corresponding to the facility ID stored in the facility information database 206a based on the facility ID included in the searched facility information stored in the searched facility information database 206c. Is updated by the input of a review comment or a review by a review reviewer corresponding to the review reviewer ID included in the selected facility information stored in the selected facility information database 206b (step SD-17) : Yes), facilities before and after renewal To generate the difference information based on the difference of the broadcast (step SD-18).

  Then, the update information generation unit 202s of the navigation server 200 indicates that the facility information of the search facility has been updated, such as “the data of the facility searched in the past has been changed” based on the update of the facility information of the search facility. Update information including the data and the display screen of the difference information generated in step SD-18 is generated (step SD-19). Here, the update information generation unit 202s may further generate update information including voice data indicating that the facility information of the search facility is updated based on the update of the facility information of the search facility.

  Then, the update information output control unit 202t of the navigation server 200 transmits the update information generated by the update information generation unit 202s to the navigation device 100, whereby the display included in the update information is displayed on the display unit 114 of the navigation device 100. A screen is displayed (step SD-20). Here, the update information output control unit 202t further transmits the update information generated by the update information generation unit 202s to the navigation device 100, so that it is included in the update information via the audio output unit 118 of the navigation device 100. Audio data may be output.
