First Claim
1. A navigation apparatus used in a vehicle for displaying positional information of said vehicle on a display screen, said apparatus comprising:
- means for storing map information which covers at least a range of movement of said vehicle;
means for detecting a position and moving direction of said vehicle;
base field display means for extracting first information from said map information based on the position and moving direction of said vehicle detected by said detecting means, and displaying said first information on a base field of said display screen such that a predetermined azimuth of said map information faces upward;
a switch used to instruct a formation of a window field in a part of said display screen;
means for instructing a shape of said window field; and
window field display means for extracting second information from said map information based on the position of said vehicle detected by said detecting means, when said switch is operated, and for displaying said second information in said instructed shape on the window field of said display screen such that the moving direction faces upward.

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.
