ABSTRACT:
A method of exchanging navigation information between a terminal, an offboard vehicle navigation device in particular, and a control center is described, the navigation information including route information for at least one route between a starting point and a destination. The method involves the following steps: a) verifying a starting point reference ID and/or starting coordinates and verifying a destination reference ID and/or destination coordinates and b) calculating route data and transmitting to the terminal a route response containing at least parts of the route data, the route data corresponding to at least one complete route from the starting point to the destination or at least one partial route from the starting point to an intermediate point located between the starting point and the destination at least as a function of the length of the route from the starting point to the destination.
