System and method for navigating a vehicle

A system for navigating a vehicle, comprising:

• (a) first means for monitoring a distance travelled by the vehicle and vehicle direction and deriving data on the instantaneous position and direction of the vehicle;
• (b) second means for storing roadmap data including configurations of a plurality of known branching points;
• (c) third means for designating a route of travel from a first known branching point through which the vehicle is first to pass to a final destination;
• (d) fourth means for determining a first road connected to the first known branching point and through which the vehicle is to arrive at the first known branching point on the basis of the present direction of the vehicle with respect to the first known branching point, derived by said first means, and based on direction data stored in said second means for each road branched from the first known branching point;
• and
• (e) fifth means for displaying on a display screen thereof a relative positional relationship between the first road and a second road branched from the first known branching point and through which the vehicle is to travel along the designated route of travel from the first known branching point.
