Abstract
Movement guidance devices and programs provide movement guidance for a mobile unit using guidance information for providing movement guidance for the mobile unit. The guidance information is delivered from a server device. The devices and programs store the guidance information delivered from the server device in a memory. The stored guidance information is area-section-by-area-section guidance information. The devices and programs set a remaining priority for the stored guidance information on a per area section basis of map information and delete, from the memory, guidance information for an area section with a low remaining priority on a priority basis rather than guidance information for an area section with a high remaining priority among the stored guidance information.
