Abstract
The invention relates to a method for generating dynamic indications relating to a modification of a route guidance. Original navigational directions are generated along an original route between a starting point and a destination. Due to modified traffic conditions, it can happen that an alternative route is preferable. Therefore an alternative route is provided which is different from the original route. According to the invention, when a vehicle is located at a current location on the original route, an alternative route to the destination is determined, comprising the location of the deviation between the original route and the alternative route. The method also comprises the generation of an acoustic indication relating to a modification of the route guidance in accordance with the zoom level of a map section, represented on a display, in respect to the location of the deviation.
