The navigation device 400 searches for a guidance route from the current position of the navigation device 400 to the position of each doorway, searches for the guidance route with the shortest time or distance as the optimum route, and a plurality of the optimum route and other guidance routes. The bifurcation point may be obtained.

  The guide route display unit 402d displays the guide route searched by the guide route search unit 402c and the current position of the navigation device 400 acquired by the current position acquisition unit 402a on the map data via the display unit 414. When the current position reaches the destination or via point within the predetermined distance or within the predetermined predicted arrival time, or the current position is within the predetermined distance or the predetermined predicted arrival time to the first branch point. When it reaches, the facility data of the facility is highlighted (step SC-4). Here, the guidance route display unit 402d may highlight the facility data by coloring it. Further, the guidance route display unit 402d may further highlight the connection facility data. The guidance route display unit 402d may distinguish and highlight both the facility data and the connected facility data. In addition, when the installation data is included in the facility data, the guidance route display unit 402d may display the installation facility data superimposed on the highlighted facility data at the position of the installation facility. Further, the guide route display unit 402d displays the optimum route searched by the guide route search unit 402c, and when the current position reaches within a predetermined distance or a predetermined predicted arrival time to each branch point of a plurality of branch points. The facility data may be highlighted.

  Above, description of an example of the process of the navigation apparatus 400 in 3rd Embodiment is finished.
