Abstract
A controller of a navigation terminal (navigation apparatus) is configured to find a plurality of paths from a current position of a vehicle and a destination based on a plurality of different and prioritized path-finding conditions, respectively, and causes a display to show the plurality of paths which includes a navigating path found on the basis of a top-priority path-finding condition and at least one alternative path found on the other path-finding condition(s). In response to detection of deviation of the vehicle, the priority assigned to a path-finding condition based on which a specific alternative path along which the vehicle is running is changed into a top priority, and path-finding operation is performed again for paths from the current position of the vehicle to the destination to show a new navigating path and at least one new alternative path in the display.
