Claim 0:
1. A navigation device that displays a guidance route to a destination on a map, comprising a processor that includes:
a map display unit configured to display a map on a first display device and display the guidance route and a current position on the map; and
a scale determination unit configured to determine a scale of the map to be displayed on the first display device,
wherein
an intersection zone of a nearest intersection at which it is required to turn along the guidance route is defined between an entrance position and an exit position,
when the current position reaches a position preceding by a first predetermined distance the entrance position of the nearest intersection, the scale determination unit lowers the scale, and further lowers the scale as the current position moves from the position preceding by the first predetermined distance and approaches the entrance position of the nearest intersection, and
when the current position enters the intersection zone of the nearest intersection from the entrance position and reaches a position of a second predetermined distance from the entrance position of the nearest intersection, the position of the second predetermined distance being within the intersection zone, the scale determination unit enlarges the scale, and further enlarges the scale as the current position moves from the position of the second predetermined distance toward the exit position through the intersection zone of the nearest intersection.
