1. A navigation apparatus comprising:
- an acquisition device for acquiring the current position of a moving body;
a registration device that is used when registering the destination to which said moving body is to reach;
a reading device in which a portable recording medium on which map data is recorded is mounted and which reads at least the map data recorded on the portable recording medium;
a setting device for setting a route to said destination based on the acquired current position, the registered destination and the recorded map data;
a memory device for storing map data used route guidance for the moving body based on the set route; and
a transfer device for transferring the map data, which has a preset geographical range that includes the road set as the route, based on the current position of the moving body and the set route from said portable recording medium to the memory device.
