A navigation system and method for guiding a vehicle along a selected route of travel to a destination from a starting point using a display unit. In the navigation system, a positional relationship between a start road branched from a first known branching point (a start intersection from which a guidance of the vehicle along the selected route of travel is initiated) and entrance direction of the vehicle toward the first known branching point is clearly and distinguishably displayed on the screen of the display unit after the selection of the route of travel from the starting point to the destination so that the vehicle can corectly enter the start road at the first known branching point even if it has reached the first known branching point via any arbitrary route of travel from the starting point.
