ABSTRACT:
A navigation system can indicate a relationship in position between a main vehicle and a related vehicle without reducing a map picture on a display unit. A second display unit (6a) is provided independently of a first display unit (3a) for a map picture in a navigation system. The second display unit (6a) indicates a position of the related vehicle by means of a direction (11) relative to the main vehicle and a distance (12) from the main vehicle to the related vehicle. Preferably, the direction (11) and distance (12) are indicated by an arrow or characters and by digits, respectively. This makes the display obvious.
