摘要： A vehicular navigation system includes a present-position sensing unit (2), an information storage unit (3), input/output means (1) for entering a destination and a transit point, designating execution of a route search from the present position sensed by the present-position sensing unit to the destination or the transit point, and a central processor (4) having route searching means for performing a route search from the present position to the destination or transit point, route storage means for temporarily storing a route that has been found, route-guidance control means which outputs a signal for performing route guidance, and route travel determination means for determining whether the present position of the automotive vehicle is on the suggested route. When execution of a route search is designated while the vehicle is traveling on the suggested route, a route different from the suggested route is retrieved.
