Abstract
A terminal apparatus has a simple map installed therein. When a map is desired, it is checked whether or not a map of a desired place exists in the simple map. If it exists, the map of the desired place is loaded from the simple map, or if it does not exist, the map of the desired place is downloaded from a navigation server.
