PROBLEM TO BE SOLVED: To solve the problem that, when a set route up to a set destination is changed, a complicated operation such as the setting operation or the like of a routing place is required and that a desired route is not set even when the routing place is set. SOLUTION: A means by which a specific branch point on the set route up to the set destination is selected, expanded and displayed is installed inside the navigation system. A road-selection processing part is installed in such a way that a road which is connected to the branch point is displayed by its name while it is being expanded and displayed and that a specific road is selected from a display list so as to be selected as a priority road from the specific branch point. |
