PROBLEM TO BE SOLVED: To provide a navigation method, a navigation device, its information providing device and a navigation system capable of guiding a route without troubling a driver even when deviating from a guided route. SOLUTION: In this navigation method, when a vehicle M (traveling locusβ) traveling along the guided routeαreaching a destination G is judged to be deviating (β') from the guided routeα, an on-vehicle device transmits present position information p and traveling direction information d after deviation to an information center. When receiving the present position information p and the traveling direction information d, the information center transmits route information for guiding a route along the traveling direction (arrow marked) of the vehicle M based on the received information p, d to the on- vehicle device. Hereby the vehicle M can travel to the destination G along a guided routeγby the route information without executing the change of direction such as U-turn or the like which is troublesome to the driver. |
