1. A host navigation device comprising:
- a first receiving section configured to receive via a communication network;
a first signal indicating a current position of a first mobile navigation device and a first destination for a user of the first mobile navigation device;
a second signal indicating a current position of a second mobile navigation device and a second destination for a user of the second mobile navigation device;
a calculation unit configured to calculate a rendezvous position for the user of the first mobile navigation device and the user of the second mobile navigation device based on;
the current position of the first mobile navigation device;
the first destination;
the current position of the second mobile navigation device; and
the second destination, the second destination being different than the first destination;
wherein the positions of the first and second mobile units are automatically updated without requiring any user interaction and wherein the actual rendezvous position may be changed according to the updated positions of the first and second mobile units; and
a transmission section configured to encode the rendezvous position in an output signal transmitted via the communications network to the first mobile navigation device and the second mobile navigation device.

Abstract
The data exchange between two or more navigation devices allows a highly automated coordination of routes of navigation devices. The calculation of a route may be based on the GPS data and additionally on the positional data received from another navigation system to provide, for example, for a rendezvous function with a minimum activity from the users of the navigation devices.

4. A method comprising:
-
receiving, from a first navigation device configured to receive and decode information to determine a current position of the first navigation device, a first set of positional data including the current position and a destination for a first user associated with the first navigation device; receiving, from a second navigation device configured to receive and decode information to determine a current position of the second navigation device, a second set of positional data including a current position and a destination for, a second user associated with the second navigation device, the destination of the second user being different that the destination of the first user; identifying a rendezvous location based at least in part upon the first positional data and the second positional data, wherein the positions of the first and second navigation devices are automatically updated without requiring any user interaction and wherein the actual rendezvous position may be changed according to the updated positions of the first and second mobile units; and communicating at least the rendezvous location to the first user via the first navigation device and to the second user via the second navigation device. - View Dependent Claims (5, 6)
