First Claim
1. A navigation system having a navigation apparatus, a server apparatus and a route information transmittance apparatus, which are capable of transferring and receiving information in bidirectional inter-communication via a communication network,(i) said route information transmittance apparatus comprising:
- an input device for inputting route search information which includes destination information and is required for performing a route search; and
a transmittance device for transmitting the inputted route search information to said server apparatus,(ii) said server apparatus comprising;
a server side communication device for receiving the route search information transmitted from said route information transmittance apparatus;
an authentication device for judging whether or not the destination information is appropriately authorized to perform the route search and identifies appropriately the destination position in performing the route search; and
a search device for performing the route search on the basis of the route search information which is judged to identify appropriately the destination position in the case where the destination information is judged to identify appropriately the destination position in performing the route search, wherein said server side communication device further transmits search result information indicating a route searched by said search device to said navigation apparatus, and(iii) said navigation apparatus comprising;
a terminal side communication device for receiving the search result information; and
a route guidance device for performing a route guidance on the basis of the received search result information.

Abstract
A navigation system (500) is provided with: a navigation apparatus (510); a server apparatus (520) and a route information transmittance apparatus (530), which are inter-communicable via a communication network (540). The route information transmittance apparatus is provided with: an input device (531) for inputting route search information indicating an instruction of a route search; and a transmittance device (532) for transmitting the route search information to the server apparatus. The server apparatus is provided with: a server side communication device (521) for receiving the route search information; an authentication device (522) for authenticating whether or not the route search information is available; and a search device (523) for performing the route search on the basis of the authenticated route search information. The server side communication device transmits search result information indicating a searched route to the navigation apparatus. The navigation apparatus is provided with: a terminal side communication device (511) for receiving the search result information; and a route guidance device (512) for performing a route guidance on the basis of the search result information.

12. A navigation method in a navigation system having a navigation apparatus, a server apparatus and a route information transmittance apparatus, which are capable of transferring and receiving information in bidirectional inter-communication via a communication network,
(i) at said route information transmittance apparatus, said method comprising: -
an input process of inputting route search information which includes destination information and is required for performing a route search; and a transmittance process of transmitting the inputted route search information to said server apparatus, (ii) at said server apparatus, said method comprising; a server side communication process of receiving the route search information transmitted at said transmittance process; an authentication process of judging whether or not the destination information is appropriately authorized to perform the route search and identifies appropriately the destination position in performing the route search; and a search process of performing the route search on the basis of the route search information which is judged to identify appropriately the destination position in the case where the destination information is judged to identify appropriately the destination position in performing the route search, wherein at said server communication process, search result information indicating a route searched at said search process is further transmitted to said navigation apparatus, and (iii) at said navigation apparatus, said method comprising; a terminal side communication process of receiving the search result information; and a route guidance process of performing a route guidance on the basis of the received search result information.
