Abstract
A road assigned with speed limit information displayed in a display unit is extracted as a determination target road. Whether congestion information for the determination target road is acquired is determined. The determination target road, for which congestion information is acquired, is extracted as a display-switching target road. A display form of speed limit information of the display-switching target road is switched from a usual display form to a congestion display form to thereby inform a user of a presence of the congestion information.
