Abstract
When there is no continuity between a current position data acquired by the car navigation system and a previous position data acquired by the car navigation system, the car navigation system determines a current position of a vehicle based on position data transmitted from a personal digital assistant (PDA). In this way, the current position of the vehicle can be determined immediately.
