Abstract
A map distribution system includes a map distribution server that distributes map data to a navigation device. The server includes a first table having entries that each include update data in correspondence with an ID for the update data and an ID for each other update data upon which the update data depends, a second table having entries that each include an area ID of an area of the map data in correspondence with a version of the area and the ID for each update data that is applied in the version of the area, and an update manager that refers to the second table to select the ID for each update data required for updating an area selected based on input from the navigation device and the required ID for each other update data upon which any update data required for updating the area selected depends.
