Abstract
An automatic navigation-system update device includes a storage unit including a first storage module and a second storage module each of which stores map data and map version information; a communication unit configured to transmit the map version information extracted from the storage unit to an update server and to receive, from the update server, differential data of map data based on a difference between the map version information and latest map version information; and a control unit. The control unit guides a route on the basis of the map data stored in the first storage module and to update the map data stored in the second storage module by reflecting the differential data.
