发明名称 Navigation apparatus
摘要 A navigation apparatus for a vehicle displays, based on map information, a map image for vicinity of a present position of the vehicle and a guidance route in superimposition in a display device. An end point relative to a moving arrow is defined as being a predetermined first distance ahead of the present position along the route; a start point is defined as being a predetermined second distance smaller than the first distance ahead of the present position along the route. The navigation apparatus is further configured to superimpose, on the displayed route, the moving arrow which includes an arrowhead and a line between the arrowhead and the present position, such that the arrowhead moves from the start point to the end point along the route when a distance to a nearest guidance point is smaller than a predetermined distance.
