In a method and a corresponding device for managing map data of a digital map for a navigation apparatus, the map data include original map data, wherein the original map data are each associated with one or more original map tiles. A validity indicator is assigned to each of the original map tiles. In the event of an update of an update map tile, associated update map data are assigned and permanently stored, wherein the particular update map tile is provided in order to replace the associated original map tile.
