The installation instructions steps MUST be followed carefully and in order. Failure to follow these
steps may result in damage to the navigation unit!
1. Connect the VCI-GM3's black power wire to chassis ground. Connect the red wire to the vehicles +12 volt accessory. The power wires are the ones coming out
from the DC 12V side of the case. If using the NAV-1129, simply connect the red wire to the retained accessory power and the black wire to the ground output.
2. Connect the VCI-GM3's Blue Trigger wire to the vehicle's +12 volt reverse light supply wire. The Reverse wire will show +12 volts when the vehicle is put into
reverse. If using the NAV-1129, simply connect to the reverse output.
3. Connect the Video Back-up Camera's video output to the VCI-GM3's Video 2 input. (Optional: The VCI-GM3's Video 1 input can be used for a second video
backup camera. The toggle switch selects between the radio's normal display or Video 1 input. Video 2 input has precedence over Video 1 input, when the blue
wire receives +12volts, regardless of the switch position.)
