Solar Angle

This screen is used to graphically display the sun's position as determined by GPS. The Navi System uses the sun's angle, along with the sunlight sensor to control the driver/passenger A/C airflow. The heat that must be removed by the A/C unit varies, depending on the angle of the sun entering the vehicle. This screen is for factory use only, and should not be adjusted.

• The screen shows a circular diagram of the sky oriented in the direction that the vehicle is pointing. During daylight hours a red dot is shown, representing the direction and elevation of the sun. The outer circle represents the horizon (0 degrees elevation). The middle circle is 30 degrees, the center circle is 60 degrees, and the very center is directly overhead (90 degrees).
• The "Auto button" should always be on (yellow).
• The "Angle", "Dir", and "Reliability" settings are used by the factory to simulate the sun's position for debugging this function.
