PROBLEM TO BE SOLVED: To bring a user to reason that the optimum route is selected for the user. SOLUTION: A route searching section searches a plurality of routes, and a route selecting section computes feature values of respective searched routes, selects an arbitrary route from the plurality of selected routes and displays the feature value of the selected route and its route map. Then, a composing section displays routes and their feature values varying in the increasing/decreasing direction of a feature value increasing/decreasing button E, in response to its operation by the user, in order to bring the user to determine the route. Therefore, since the user checks the searched route maps and their feature values, evaluates respective searched routes and determines the route, the user can reason that the optimum route is selected for the user.
