The present invention is directed to a navigation apparatus capable of performing a proper voice guidance even in such a case that signals transmitted from GPS satellites cannot be received, but a current location cannot be judged. That is to say, the navigation apparatus of the present invention is featured by such a navigation apparatus in which signals transmitted from GPS satellites are received so as to measure a current location, the measured current location is displayed on a screen in connection with a map, a guidance route up to a destination place is set, and a guidance is notified every predetermined guidance point. In this navigation apparatus, when the signals transmitted from the GPS satellites cannot be received, if a current location is located on the guidance route, then a virtual current location is displayed in such a manner that the virtual current location is moved on the guidance route at a predetermined speed, and a guidance is notified every predetermined guidance point. <IMAGE> |
