A navigation apparatus for navigating a vehicle in accordance with a preset course while measuring distance travelled and steering angle is characterized by presetting distance information for guidance along the course, and outputting guidance relating to the pertinent distance information in the form of travelling conditions corresponding to the preset distance information. Distance information for guiding a driver along the course is preset. Therefore, even if it is a long distance to an intersection at which the next turn is to be made, whenever the vehicle has traveled a fixed distance the driver is unfailingly supplied with distance information relating to the intersection at which the next turn is to be made and with distance information relating to distinguishing features seen along the course, such as facilities and scenery, during the time the vehicle is travelling between the intersections. Thus, if a long distance must be travelled to reach the intersection at which the next turn is to be made, the driver is frequently supplied with guidance relating to distance information while traveling. This makes it possible for the driver to verify the course and assures that the driver can drive the vehicle at ease without requiring that he be aware of the distance to the intersection at which the next turn is to be made.
