Abstract
A navigation apparatus used in a vehicle and associated display method are designed to spot the current position of the vehicle on maps displayed in a base field and a window field of a display screen. The apparatus includes a memory for storing map information and sensors for detecting the position and moving direction of the vehicle. A portion of the map information is retrieved from the memory in accordance with the sensor outputs and displayed in the base field such that certain azimuth, e.g., the north, faces upward. Another portion of the map information is retrieved from the memory and displayed in the window field such that the moving direction faces upward.
