1. A navigation system comprising a centralised server having access to roadmapping data relating to at least one given geographical zone and enabling a plurality of routes to be determined in this zone, and a plurality of mobile navigation devices, capable of communicating at least temporarily with the central server to exchange mapping and/or route data, wherein the centralised server comprises:

  • at least one microprocessor;

    at least one working memory;

    a data exchange module;

    a route calculation module;

    a navigation window generation module, enabling the route data to be formatted into a plurality of successive fixed windows, each comprising one or more route instructions; and

    an exit detection data generation module, enabling exit detection points to be generated, enabling an exit detection module of a mobile navigation device to detect a possible exit from the route according to the real position of said mobile navigation device during the movement to travel the intended route;

    and wherein the mobile navigation devices comprise;

    at least one microprocessor;

    at least one working memory;

    a data exchange module;

    a navigation module, to provide the transmission to the user of the successive navigation windows according to the real position of said mobile device;

    a geolocation module, enabling the real position of the mobile navigation device to be determined during the movement of the latter;

    a matching module, enabling a correspondence to be established between the real position supplied by the geolocation module and the intended route; and

    a route exit detection module, enabling the possible exits from the intended route to be detected during the movement of the mobile device.
