    means for finding a plurality of paths from the current position of the vehicle identified by the locator to a destination input by the operator and received through the input interface, based on a plurality of different path-finding conditions, respectively;

    means for causing the display to show the plurality of paths which comprise a navigating path found on the basis of a top-priority path-finding condition and at least one alternative path found on the basis of a path finding condition other than the top-priority path-finding condition; and

    means for changing priorities assigned to the path-finding conditions in response to detection of deviation of the vehicle based on the current position identified by the locator, wherein if the current position indicates that the vehicle is running along a specific alternative path, then the priority assigned to a pass-finding condition based on which the navigating path has been found is changed into one other than a top priority, and the priority assigned to a pass-finding condition based on which the specific alternative path has been found is changed into the top priority.
