PROBLEM TO BE SOLVED: To provide a navigation device in which the calculation accuracy of the total required time for route searching is improved by adapting driving tendencies of a driver and actual traffic conditions. SOLUTION: The device comprises a means to obtain and memorize driving tendencies to left and right turns of a driver; and a correction means to correct parameters for time required for left or right turn corresponding the driving tendencies of the driver, and calculates the total required time using the corrected parameters for time required for left or right turn. By reflecting the driving tendencies of the driver to a required time for route searching, the calculation accuracy of the total required time for route searching can be improved.
