Navigation apparatus and navigation program

Abstract

A navigation device includes a history information storage unit, a history information extraction unit, and a guidance information output unit. The history information storage unit stores history information on at least a guidance object. The history information is acquired from a record of previous navigation operations of the navigation device. When a branching point and an approach road to the branching point have been designated, the history information extraction unit extracts from the history information storage unit the history information on a guidance object that exists in at least one direction in which the navigation device can proceed from the branching point. The guidance information output unit outputs both (i) direction guidance information on said at least one direction and (ii) history guidance information that, in association with the direction, provides guidance for the guidance object that corresponds to the extracted history information.
