Abstract: The present invention provides, in a car navigation system, a unit of notifying a user of the update contents of map data prior to the downloading of the map data. A vehicle-mounted terminal sets a difference update area in accordance with a selection made by a user and sends a difference update request to a map updating server. If an update mode in this case is “update after outline display”, the vehicle-mounted terminal downloads an outline update map from the map updating server. The outline update map is displayed on a display unit of a display. Here, when a download start button displayed on the display unit is depressed, the vehicle-mounted terminal downloads a detailed update map from the map updating server. The detailed update map is then displayed on the display unit of the display. Furthermore, an updating process is performed on the map data stored in a terminal DB.

Abstract: In a communication type navigation system that downloads maps, the present invention provides a map data transmission method that can reduce time before guiding is started. A map provision server searches for a traveling route connecting a starting place corresponding to current position information received from an on-vehicle terminal and a destination corresponding to destination information. The server generates guidance information for guiding the vehicle along the searched traveling route and generates a route vicinity map along the traveling route. The server generates traveling route information comprising the searched traveling route and the guidance information, and plural map information blocks into which the route vicinity map containing map information is divided along the traveling route, assigns transmission priority levels to the map information blocks, and transmits the map information blocks according to the transmission priority levels after transmitting the traveling route information.

Abstract: The present invention provides, in a car navigation system, a unit of notifying a user of the update contents of map data prior to the downloading of the map data. A vehicle-mounted terminal sets a difference update area in accordance with a selection made by a user and sends a difference update request to a map updating server. If an update mode in this case is “update after outline display”, the vehicle-mounted terminal downloads an outline update map from the map updating server. The outline update map is displayed on a display unit of a display. Here, when a download start button displayed on the display unit is depressed, the vehicle-mounted terminal downloads a detailed update map from the map updating server. The detailed update map is then displayed on the display unit of the display. Furthermore, an updating process is performed on the map data stored in a terminal DB.

Abstract: In a communication-based navigation system, even when a vehicle deviates from an original guidance route, an in-vehicle terminal device can locate a new guidance route and display the same without receiving another guidance route delivered from a server device. Immediately after searching for a guidance route which is displayed at the start of running, the server device finds data on the shortest route from each node to a destination (direction data to return to the original route) in accordance with a shortest path algorithm, and delivers this data to the in-vehicle terminal device together with delivery map data including the guidance route. When the vehicle deviates from the guidance route, the in-vehicle terminal device locates a new guidance route or a return route from the location at which the vehicle deviates based on the direction data to return to the original route, and displays the guidance route or return route.
