Video 1 input if applicable).
Testing the VCI-GM3:
1. Turn the vehicle and radio on. The radio display should show normal information.
* If there is no image on the display, check for correct power connection on the VCI-GM3.
* If the image on the display scrolls across the screen, make sure the ribbon cable is seated in the connector correctly.
2. Temporarily put the vehicle into reverse being careful not to back into anything or anyone. The display screen will change to the video back-
up camera mode. Put vehicle back to Park and the radio display should show normal information.
*If the radio screen information disappears and you get a blank screen when the vehicle is put into reverse, check the video back-up
camera for proper power and video cable connection.
*The camera must be connected to Video 2 Input.
