1. A navigation apparatus comprising:

  • a host vehicle location acquisition unit configured to acquire a current location of a host vehicle;

    a route guidance unit configured to perform a route guidance process for guiding the host vehicle along a guidance route from the current location of the host vehicle to a destination based on the current location of the host vehicle and map data indicative of road connections, wherein the current location of the host vehicle is acquired by the host vehicle location acquisition unit;

    a display control unit configured to control a display of an intersection guidance image, wherein the intersection guidance image provides a guidance on an intersection to be possibly travelled by the host vehicle;

    a sign image acquisition unit configured to acquire a direction sign image, wherein the direction sign image is an image of a direction sign that indicates leading directions of roads connected to the intersection; and

    an intersection enlarged view acquisition unit configured to acquire an intersection enlarged view, wherein the intersection enlarged view is an image providing a guidance on a traveling direction of the host vehicle at a target intersection located in forward direction of the host vehicle along the guidance route, the intersection enlarged view includes symbols indicative of facilities serving as landmarks of the target intersection,the display control unit displays, as the intersection guidance image, a direction sign image corresponding to the target intersection prior to the intersection enlarged view of the target intersection during the route guidance process which is performed by the route guidance unit,during the route guidance process which is performed by the route guidance unit, the display control unit;

    displays the intersection enlarged view as the intersection guidance image when a remaining distance between the host vehicle and the target intersection is within an enlarged view display distance; and

    displays the direction sign image corresponding to the target intersection as the intersection guidance image while the host vehicle travels toward the target intersection within a segment defined between a point prior to an installation location of a direction sign of the target intersection by a sign display distance and a point prior to the target intersection by the enlarged view display distance, andthe sign display distance and the enlarged view display distance are preliminarily set so that the sign display distance is longer than the enlarged view display distance.
