1. A navigation system comprising:
- a position data receiving means for receiving at least one set of position data from a hand-held terminal, wherein each set of the position data indicates a position of the hand-held terminal; and
a control means, which executes at least one predetermined process based on the at least one set of the position data received by the position data receiving means.

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.

4. A data transfer system comprising a hand-held terminal and a navigation system, wherein:
-
the hand-held terminal includes;
a position data acquiring means for acquiring at least one set of position data, wherein each set of the position data indicates a position of the hand-held terminal;
a position data transmitting means for transmitting at least one of the at least one set of the position data acquired by the position data acquiring means; and
a control means, which transmits the at least one of the at least one set of the position data acquired by the position data acquiring means from the position data transmitting means to the navigation system; and
the navigation system includes;
a position data receiving means for receiving the at least one of the at least one set of the position data from the hand-held terminal; and
a control means, which executes at least one predetermined process based on the at least one of the at least one set of the position data received by the position data receiving means. - View Dependent Claims (5, 6, 7)

8. A hand-held terminal of a data transfer system, wherein the data transfer system includes the hand-held terminal and a navigation system, the hand-held terminal comprising:
-
a position data acquiring means for acquiring at least one set of position data, wherein each set of the position data indicates a position of the hand-held terminal;
a position data transmitting means for transmitting at least one of the at least one set of the position data acquired by the position data acquiring means;
a control means, which transmits the at least one of the at least one set of the position data acquired by the position data acquiring means from the position data transmitting means to the navigation system;
a clocking means for clocking date and time; and
a position data storage means, which stores the at least one set of the position data acquired by the position data acquiring means, wherein;
the control means stores each set of the position data, which is acquired by the position data acquiring means, in the position data storage means together with associated date and time of acquisition of each set of the position data clocked by the clocking means; and
when the associated date and time of one of the at least one set of the position data are specified by a user, the control means transmits the corresponding set of the position data from the position data transmitting means to the navigation system. - View Dependent Claims (9)

10. A hand-held terminal of a data transfer system, wherein the data transfer system includes the hand-held terminal and a navigation system, the hand-held terminal comprising:
-
a position data acquiring means for acquiring at least one set of position data, wherein each set of the position data indicates a position of the hand-held terminal;
a position data transmitting means for transmitting at least one of the at least one set of the position data acquired by the position data acquiring means;
a control means, which transmits the at least one of the at least one set of the position data acquired by the position data acquiring means from the position data transmitting means to the navigation system;
a character inputting means, through which associated characters are inputted for each set of the position data by a user; and
a position data storage means, which stores the at least one set of the position data acquired by the position data acquiring means, wherein;
the control means stores each set of the position data, which is acquired by the position data acquiring means, in the position data storage means together with the associated characters of each set of the position data; and
when the associated characters of one of the at least one set of the position data are specified by the user, the control means transmits the corresponding set of the position data from the position data transmitting means to the navigation system. - View Dependent Claims (11)
