Abstract:
1. A method for operating a navigation system, said navigation system including: an input device for inputting operator commands and/or location information including starting points and/or destinations, a road network database, a route calculating unit for calculating a planned route with consideration of the location information and the road network database, wherein the route leads from the starting point to the destination, a signal receiving unit for receiving position signals, a position finding unit that determines the current position from the position signals, and at least one optical and/or acoustical output device for optically and/or acoustically outputting a simulated route preview in a simulation mode, wherein the simulated route preview simulates the route navigation from a starting point to a destination, wherein said method comprising the following steps: a) inputting a destination; b) deriving a starting point from the destination being input by utilizing a starting point derivation rule, wherein the starting point derivation rule specifies that the derived starting point lies in the same city or in the same town as the destination being input; c) calculating a route from the derived starting point to the destination being input; and d) outputting the simulated route preview from the derived starting point to the destination being input.
