ABSTRACT:
A navigation device is provided for easily designating a road to be avoided with high accuracy. When a location on a map is designated by a touch panel7,an avoidance-road setting unit22identifies a road existing at or near the location designated, and specifies a link corresponding to the road. Then a map drawing unit14draws a map image in a reduced scale larger than that previously set. If another location on the map is designated, the process of specifying the link and the process of drawing the map image in the larger reduced scale, which are described above, are repeated. When there is provided an instruction to set the road specified based on the location as an avoidance road, the avoidance-road setting unit22stores a link ID of the link corresponding to the specified road in an avoidance-road memory24.
