Abstract
A navigator receives, through communication with a server, only such map information or locality information as is considered to be necessary, and stores it by overriding with it already used map information and locality information. Thus, the navigator, despite having a small storage capacity, is free from interruption of display. Receiving minimum needed information helps save the communication charge.
