Abstract
A navigation system has a first communication terminal unit; a second communication terminal unit which communicates with the first communication terminal unit; and a car navigation apparatus. The first communication terminal unit transmits the self-location information to the second communication terminal unit. The second communication terminal unit receives the location information transmitted from the first communication terminal unit; and transfers the received location information to the car navigation apparatus. The car navigation apparatus sets up a destination on the basis of the location information transferred from the second communication terminal unit and searches for the route up to the destination.
