First Claim
1. A vehicle navigation apparatus for simultaneously displaying a first map and a second map which differs from the first map in representation form, said navigation apparatus comprising:
- a display;
map display means for displaying said first map and said second map at different display areas of said display;
current position calculation means for calculating a current position of the vehicle;
current position display means for displaying a current position mark indicative of the current position calculated by said current position calculation means on at least one of the first map and the second map displayed by said map display means; and
position specification accepting means adapted to accept a specification of a position in the display area with the first map being displayed thereon from a user, wherein said map display means is adapted to display the second map in such a form that a position on the second map representing the same point as a point on the first map is identifiable, the point on the first map corresponding to the position whose specification is accepted by said position specification accepting means.

Abstract
A navigation apparatus for simultaneously displaying a first map and a second map which differs from the first map in representation form includes a map display means for displaying the first map and the second map at different display areas of the display, and a position specification accepting means adapted to accept the specification of a position on the display area with the first map being displayed thereon from a user. The map display means is adapted to display the second map in such a form that a position on the second map representing the same point as the point on the first map is identifiable, the point on the first map corresponding to the position whose specification is accepted by the position specification accepting means. This enables the user to easily identify the position of the point on the second map corresponding to the point specified on the first map.
