The apparatus and method determine whether a guidance route (R1) includes the first point and the second point of a stored route. The apparatus and method read out, if a guidance route includes the first point and the second point of a stored route, the stored route information for the stored route that shares the first point and the second point with the guidance route. If the read out stored route information has a same or similar traffic condition as a current traffic condition, the apparatus and method output the required time to travel the stored route from the read route information.",
