Abstract
A method of demonstrating navigation for a vehicle navigation apparatus while drawing a map of an arbitrary region limits wear and tear on a CD-ROM drive. When map data for demonstration is read out from a CD-ROM, the map data is stored in a memory and the demonstration is performed. Thereafter, if the demonstration is to be repeated, it is performed by reading out the map data stored in the memory. A demonstration process of reading, from the CD-ROM, data of a map showing a region in which a route along which navigation is to be demonstrated is selected. The functions of the navigation apparatus are presented while displaying the map, so that when a demonstration region is selected, a corresponding demonstration route is created in the demonstration region, and a navigated vehicle mark is moved along the demonstration route while the corresponding map is displayed.
