Abstract
A navigation device for setting an appropriate navigation route based on a support route while reducing an amount of communicating information, is provided. The navigation server recognizes a departure position and a destination position of a user, and sets a support route connecting the departure position and the destination position, based on communication with the navigation device. The navigation device recognizes multiple links constituting a part of the support route, based on communication with the navigation server. The navigation device sets a navigation route including the links connecting the departure position and the destination position. The navigation device determines whether a deviation between a distance of an adjacent link pairs among the links along the support route and a distance thereof along the navigation route is equal to or less than a threshold value. The navigation route is output via an output device if the determination result is positive.
