Abstract
A navigation system includes a plurality of navigation devices and a server. The plurality of navigation devices is used for generating a plurality of position data respectively. Each navigation device generates at least one path data according to the plurality of position data and at least one corresponding electronic map and transmits the path data to the server. Then, the server calculates at least one optimum path data and updates the plurality of navigation devices according to the optimum path data.
