Abstract: A navigation apparatus includes a satellite positioning section for calculating a present position, and a route setting section for searching for a route to a destination based on map data, and sets a detected route as a recommended route. A satellite positioning disable time guiding section sets as a focus point, a candidate point through which a vehicle first passes when traveling along the recommended route, and displays point guide information for guiding the focus point among candidate points as a route change point, when the satellite positioning section is incapable of calculating the present position.

Abstract: An internet service server transmits an information link mail to a cellular phone through a cellular phone mail server. If the received e-mail is an information link mail, the cellular phone transfers it, for example, to a navigation apparatus. Upon receipt of the information link mail, the navigation apparatus starts a predetermined application and provides a service to a user. The cellular phone may start a predetermined application and store predetermined information in the cellular phone. The cellular phone can communicate with an authentication apparatus through a wireless tag reader. The authentication apparatus checks predetermined information and performs authentication as a result of the check.

Abstract: There are provided a point search apparatus and an in-vehicle navigation apparatus capable of searching destination candidates from which a user can view a visual target that he/she desires. A search means is formed so as to search destination candidates from which the user can see a visual target specified by visual target specifying means based on information regarding the three-dimensional position of the visual target and information regarding the three-dimensional position of a point that fulfills a search condition determined by a search condition determining means, and which exists around the visual target.
