The invention relates to a method for updating a digital map of a mobile navigation system, in particular a navigation system of a motor vehicle, wherein the updating of map data is improved with respect to the availability of current map data and the minimization of the data volume to be transferred (and thus also the avoidance of the updating of map data that are not required at all). For this purpose, a geographic region comprised by the digital map is divided into a plurality of regions, wherein map data of the digital map represent respective regions, wherein at least one of the regions has a first boundary line directly surrounding the region, wherein the region has an additional boundary line, which surrounds the region with greater distance than the first boundary line at least in some sections. The method comprises the following steps: determining a geographic position of the navigation system, checking a first condition of whether the position of the navigation system lies on or within the additional boundary line, and, if the first condition arises, updating the map data of the region.
