1. A vehicle navigation apparatus adapted to have a storage unit for storing map information, and configured to display a travel route from a current position to a destination based on the map information, the apparatus comprising:
- a display unit for displaying a map and the travel route based on the map information;
a first screen control that controls the display unit to display a first screen having a plurality of edit points between the current position and the destination, the edit points being on the travel route, for changing the travel route based on a user operation;
a set unit for setting an edit start point and an edit end point respectively to one of the edit points provided on the first screen between the current position and the destination on the travel route according to a user operation;
a move unit for moving, according to the user operation, a reference point from an initial position selectively set to one of the edit points between the edit start point and the edit end point on the travel route being displayed on the display unit, toward a different position on the map being displayed on the display unit; and
a revision unit for revising the travel route within bounds defined by the edit start point and the edit end point, based on each of (a) a position of the reference point having been moved by the move unit on the map, (b) the edit start point and the edit end point respectively set by the set unit, (c) a move direction of the movement of the reference point, and (d) the map information.

Abstract
The navigation apparatus has a display unit ready to accept a user operation that moves a reference point of a navigation route already being defined on a map by the apparatus. The move of the reference point of the navigation route according to the user operation, together with map information, defines a new navigation route that incorporates route amendments. The navigation apparatus thus allows the user to easily and responsively modify an already-defined navigation route in a novel manner, which enables a rubber-banding of the already-defined navigation route.
