Abstract
Even when the present position does not exist on a guide road after deviation from an established guide route, a guide road is identified and a more advantageous route is identified. Furthermore, only a minimum amount of required data are displayed on the map picture. The searching again is executed by taking the direction of progress of the car into consideration. Street names of the roads are displayed on the guide map, enabling a guide route to be easily recognized. A particular area is specified by a postal code number or by a telephone number, and the streets or the facilities in the specified area are displayed. This makes it easier to search the destination.
