发明名称 Navigation apparatus.
摘要 <p>A navigation apparatus for navigating a vehicle in accordance with a preset course while measuring distance travelled and steering angle has voice track indication means in which voice track indications corresponding to the distance remaining to an intersection at which the next turn is to be made are outputted as the intersection is approached. When the distance from this intersection to the next intersection requiring a turn is less than a predetermined value, a voice track indication pointing out a lane into which the vehicle should be steered following the turn at the former intersection is outputted after the final voice track indication given just before the vehicle reaches this intersection. When it is required that a turn be made at the latter intersection immediately after the turn at the former intersection, the lane information for the turn at the latter intersection is outputted before the vehicle is turned at the former intersection.</p>
