[0059] Next, the operation of the first embodiment will be described.
[0060] The on-board terminal 1 transmits a profile reproduced by the profile recording-reproducing means 6 to the center system 8 through the communicating means 4.
[0061]
FIG. 2 is a table showing an example of profiles of the first embodiment. In FIG. 2 the table contains an unique information category indicative of relevant information concerning a navigating application, and categories of the unique information and various information fallen under these categories. The unique information category includes user personal information 21 containing a name, sex, a blood type, an address, and so on-board information 22 as static information unique to a vehicle, containing a registration number, a vehicle type, a model, and so on-board information 23, as dynamic information indicative of a traveling state, containing a traveling distance, traveling history, and so on; terminal information 24 of the terminal itself containing a terminal name, a screen size, a CPU, a memory, and so on; service information 25 containing a category of business, substance of duties and responsibilities, and so on; and operation history information 26 of the operation history of the on-board terminal 1 containing a data version, a menu item, a service area, and so on.
[0062] In the center system 8, by using the profile received through the communication means 9, the transmission data determining means 10 determines transmission data containing relevant information to be transmitted, among a plurality of transmission data corresponding to a plurality of relevant information stored in the transmission data storing means 11, and then transmits the determined transmission data to the on-board terminal 1 through the communicating means 9.

In FIG. 5(c), map data 47 with additional data of node 1 is generated from the map data 41, and additional data 46 of node 1 (relevant information) received as additional data.
[0069] FIGS. 6(a) to 6(c) are explanatory drawings, each showing an example of transmission data stored in the transmission data storing means 11 of the center system 8 in FIG. 1. In FIG. 6(a), relevant information concerning the navigating application, such as the latest difference data, customized data, additional data and the like, is stored in each plural areas, and the latest differences data of plural versions (1st, 2nd,,, n-th generation) are stored as the latest difference data. In FIG. 6(b), the structure of the customized data in FIG. 6(a) is shown, which contains customized data corresponding to a terminal, a vehicle type, an individual, a category of business, and so on. In FIG. 6(c), the structure of the additional data in FIG. 6(a) is shown, which contains additional data for sightseeing, individual use, a category of business, and so on.
[0070] FIGS. 7(a) to 7(c) are explanatory drawings, each showing a specific example of the customized data in FIGS. 6(a) to 6(c). Specifically, FIG. 7(a) shows the structure of the customized data corresponding to a terminal; FIG. 7(b) the structure of the customized data corresponding to a service; and FIG. 7(c) the structure of the customized data corresponding to a vehicle type, i.e., vehicle information.
[0071] The transmission data determining means 10 of the center system 8 determines data among those shown in FIGS. 6(a) to 6(c) and FIGS. 7(a) to 7(c) based on the received profile. For example, if the profile indicates a terminal type AA, the transmission data determining means 10 determines, as transmission data, customized data corresponding to the terminal corresponding to the terminal type AA among the customized data corresponding to the terminal, and then transmits the determined customized data to the on-board terminal 1 through the communicating means 9.
[0072] As mentioned above, according to the first embodiment, by transmitting or receiving only the necessary relevant information between the transmitting and receiving sides for transmitting or receiving the relevant information concerning the navigating application, it is possible to shorten communication time, and reduce communication costs and the quantity of data held in the on-board terminal side.
[0073] Further, according to the first embodiment, the profile specifying the relevant information stored in the center system 8 is recorded by the profile recording-reproducing means 6 of the on-board terminal 1. Thus, the on-board navigation terminal 1 can easily obtain the specified relevant information only by transmitting the profile to the center system 8.
[0074] Further, according to the first embodiment, since the necessary relevant information is difference information indicative of a difference between the conventional map and the newly changed latest map, it is not necessary to transmit or receive all the latest map data consisting of an enormous quantity of data. Thus, it is possible to shorten communication time, and reduce communication costs and quantity of data held in the on-board terminal side.
[0075] Furhermore, according to the first embodiment, since the necessary relevant information is one corresponding to the unique information of the on-board navigation terminal side, it is not necessary to transmit or receive any wasteful relevant information, which is never used. Thus, it is possible to shorten communication time, and reduce communication costs, and the quantity of data held in the on-board terminal side to a minimum.
[0076] Moreover, according to the first embodiment, the necessary relevant information is additional information added to the navigating application. Thus, it is possible to shorten communication time, reduce communication costs and the quantity of data held in the on-board terminal side, and enhance applicability of application.
