<p>An objective of the present invention is to provide a navigation device and a server device with which, when a new site is added after a path to a destination is set, it is possible to compute an optimal path which takes a user's intentions into account. A navigation device according to the present invention comprises: a sensor information input unit (112) which receives input of sensor information from at least one or more sensors in order to identify the present location of the navigation device; a present location identification unit (115) which, on the basis of map information and the sensor information, identifies the present location on a map of the navigation device; and a path computation unit (116) which computes a path from the present location to a prescribed site. When, in a state in which a preexisting path to a preexisting destination has already been computed, a new prescribed site is designated and a new path is recomputed, the path computation unit (116) applies a prescribed condition which is set when searching out the existing path when recomputing the new path, and computes including a change of a course order of the preexisting destination or a preexisting hub in the preexisting path.</p> |
