Overview of display unit

• The display unit communicates with the navigation unit over its own GA-Net bus. Information sent by the navigation unit to the display unit includes commands to control the LCD back light.
• The navigation unit also sends navigation and rear camera video information to the screen using Red, Green, Blue and Composite Video signals.
• The security system protects the display by daisy-chaining the security signal through it, and then passing the signal to the audio unit.
• The illumination input from the gauge brightness control provides back lighting for the buttons surrounding the screen.
