Adjusting picture quality:
VIDGM1V4 module is equipped with brightness,
color and contrast adjustments.

Reinstall radio and test operation
A.
Reconnect factory radio connectors and reinstall radio.
B.
If you have installed a rearview camera, start the vehicle, turn on the radio and
navigation system and put the vehicle in reverse. The navigation display should
change to show the view from the camera. Shifting the vehicle out of park
should return you to the navigation display. If necessary, adjust the brightness,
color and contrast with the controls on the VIDGM1V4.
B.
If you have installed a video system, with the vehicle in park gear, and the
parking brake on, activate the video source. The navigation display will change
to show the video source.
C.
With the video source active and playing, test the video interlock by taking off
the parking brake. The navigation display should return.
