摘要： 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.

摘要： In a navigation apparatus for a vehicle, a route is determined in an ordinary-road-preferential mode or a toll-road-preferential mode, and route guidance is provided based on the thus-determined route. When the vehicle deviates from the determined route, redetermination is conducted so as to obtain a new route based on which guidance is provided. For example, when the vehicle has deviated from a route determined in the ordinary-road-preferential mode in order to enter a toll road, the user operates a toll-road-preference ON touch button so to change the determination mode to the toll-road preferential mode, so that route redetermination is carried out in a state in which priority is given to toll roads. In the navigation apparatus, optimum interchanges of a special road are automatically searched, and a route that preferentially uses the special road is calculated.

摘要： According to the invention, when a target name is inputted using characters such as alphabet and numerics, strings of characters or numerics are compared with data of registered places each time one character is inputted, names of registered places including the inputted string of characters or numerics is listed, and the number of registered target names remaining on the list is displayed. When the target name is inputted in characters, the inputted data is compared with a list of the registered names having word components arranged in different orders with respect to a single official name by a forward match comparison, and the number of registered target names remaining on the list with forward match is displayed. When the number of the inputted characters or numerics increases and the number of registered target names remaining on the list decreases, a list of the registered place names is displayed. The target name is selected from this list. When the number registered target names remaining on the list is one, the target name is selected. A map of the vicinity of the target name thus selected is displayed.

摘要： Navigation apparatuses, methods, and programs having conducted a search for an original driving route that goes through a plurality of destinations in a designated order and provided route guidance based on the original driving route, receive an input of a new destination. Upon receipt of the new destination, the apparatuses, methods, and programs designate an ordinal position of the new destination in terms of the designated order and receive an input of a destination change request. When the destination change request is received, the apparatuses, methods, and programs automatically delete one or more of the destinations in ordinal positions within the designated order that are before the ordinal position of the new destination, conduct a new search for a new driving route based on the new destination, and output the new driving route. When an added destination request is received, the apparatuses, methods, and programs conduct a search for the new driving route including the new destination, without deleting destinations in ordinal positions within the designated order that are before the ordinal position of the new destination.

摘要： Devices and methods search for a route from a departure point to a destination and provide guidance based on the route that is found. The devices and methods associate a street name with a parcel in which map data is associated with an area that is bounded by specified coordinates and, when the street name is input, extract the parcel in which the street name is located. The devices and methods extract a city area name in the extracted parcel and display the city area name such that the city area name can be selected. The devices and methods extract a local area name that is included in the parcel in which the selected city area name is located, display the local area name such that the local area name can be selected, and specify a house number within the parcel in which the selected local area name is located.

摘要： A system for executing guidance to a destination properly even if the destination is connected to a non-guidance target road, such as a small street. The system has a judgment device for determining whether a road connecting to a destination on the searched route is a non-guidance target road, a controller for determining a guidance terminating point on the basis of the determinative result of the judgment device, wherein if a road connecting to a destination is a non-guidance target road as determined by the judgment device, then the last intersection point of the guidance target road to the non-guidance target road or a road end closest to the departure side of the non-guidance target road is determined as a guidance terminating point.

摘要： The invention provides a vehicular navigation system which is capable of lowering the cost of detecting road data stored in order in the outgoing trip, using the road data as resources in the return trip, and determining a route meeting the requirements of the user. According to a vehicular navigation system of the invention, when a vehicle is traveling on a road having bidirectional data along an outgoing route from a starting point to a destination, a road on the opposite side of the road on which the vehicle is traveling is stored as return route data with a lowered cost of route determination. Such a storing operation is performed for each node passed by the vehicle. The return route data thus stored are used to determine a return route.
