MONITOR CHECK

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.

These screens allow you to troubleshoot the display unit. Select the item you want to troubleshoot, and
follow the diagnostic instructions.

RGB Color

This screen verifies that the display unit is receiving the video (R, G, B and Composite sync) signals
properly. The three primary colors should all be shown without distortion. The combination of all three
should produce a central white section. If any of the colors are missing, troubleshoot for the color signal (see
PICTURE IS MISSING A COLOR OR TONE OR IS AN ODD COLOR ). If the picture has lines in it
or scrolls horizontally, or vertically, troubleshoot for a Composite sync problem (see PICTURE HAS
LINES OR ROLLS ).
