Method to assist navigation by means of a navigation system comprising the steps of: - providing a digitized map, - determining whether the navigation is performed in an area which is known to a user, and (i) if this is not the case: - determining a route based on two waypoints and the digitized map, and - outputting navigation information about the route; and (ii) if this is the case; - determining a static route and corresponding navigation information including manoeuvre steps based on at least two waypoints and static road information from the digitized map or by uploading a route into the navigation system from a storage medium, - determining a dynamic route and corresponding navigation information including manoeuvre steps based on the static road information from the digitized map and time-dependent dynamic information, - formatting the navigation information differently for the static route and for the dynamic route, - determining current position data, - if the current position data corresponds to a waypoint on both the static and the dynamic route, comparing a following manoeuvre step of the static route and a following manoeuvre step of the dynamic route and - outputting the formatted dynamic route navigation information about the following manoeuvre step optically and acoustically, if the manoeuvre steps are different, - outputting the formatted static route navigation information about the following manoeuvre step optically or not outputting such navigation information at all, if the manoeuvre steps are not different. - providing a digitized map, - determining whether the navigation is performed in an area which is known to a user, and (i) if this is not the case: - determining a route based on two waypoints and the digitized map, and - outputting navigation information about the route; and (ii) if this is the case; - determining a static route and corresponding navigation information including manoeuvre steps based on at least two waypoints and static road information from the digitized map or by uploading a route into the navigation system from a storage medium, - determining a dynamic route and corresponding navigation information including manoeuvre steps based on the static road information from the digitized map and time-dependent dynamic information, - formatting the navigation information differently for the static route and for the dynamic route, - determining current position data, - if the current position data corresponds to a waypoint on both the static and the dynamic route, comparing a following manoeuvre step of the static route and a following manoeuvre step of the dynamic route and - outputting the formatted dynamic route navigation information about the following manoeuvre step optically and acoustically, if the manoeuvre steps are different, - outputting the formatted static route navigation information about the following manoeuvre step optically or not outputting such navigation information at all, if the manoeuvre steps are not different.
