Abstract
A navigation apparatus reduces route search time while providing guidance in conformity with drivers' preferences, by selectively conducting either a full-range route search or a more limited, local area search, in accordance with detected conditions and responsive to occurrence of an off-route event. For example, the full-range route search is conducted pursuant to a determination that the vehicle has gone straight at a predetermined number of certain intersections where current guidance has directed a turn.
