1. Method for operating a navigation system comprising the following method steps of:

  • a) calculating a route from a point of departure to a destination, said route being composed of a succession of route segments and junctions between the route segments and being selected by means of a route calculation process from a database in which a geographical region is described by route segments and junctions;

    b) calculating a maneuvering instruction sequence which contains instructions for the user to follow the route starting from the current position, the maneuvering instruction sequence is retrieved and output from a database;

    c) optically and/or acoustically outputting the maneuvering instruction sequence in an output device;

    characterized in thatprior to the calculation and output of the maneuvering instruction sequence, at least two human-readable configuration files are read and interpreted by an interpretation module associated with a software platform utilized for the navigation system;

    wherein preset data for calculating and/or for outputting the maneuvering instruction sequence are stored in the configuration files and define a decision logic for determining the maneuvering instruction sequence and a temporal flow chart of the maneuvering instruction sequence;

    wherein during calculation of the maneuvering instruction sequence includes performing a coarse classification of an intersection or a road section on the route;

    wherein the interpretation module includes machine-readable source code processed by a microprocessor and software platform to enable utilization of the configuration files on different software platforms;

    wherein storage of the preset data in the configuration files is performed independently of the software platform and the configuration files are read by the interpretation module as a function of a user croup or user profile to adapt the calculation and output of the maneuvering instruction sequence to the corresponding configuration file, the configuration files manipulating the behavior of the navigation system by modification or selection thereof without the need for restarting the navigation system.
