GMUNLOCKPRO OPERATION WHILE IN MULTI-CAMERA MODE
When switch 2 is in the UP position on the GMUNLOCKPRO module, the interface will
allow operation of left and right cameras automatically and manually. When switch 4 is
UP, a front camera will automatically activate when the vehicle slows below 8 mph and
turn off when the vehicle accelerates. The advanced properties of the GMUNLOCKPRO
allow it to control and power all camera functions making an installation of this type
amazingly simple.
• Switch 4 UP - When the vehicle is started up and placed in DRIVE, the front camera is
automatically activated and will display on your navigation screen a view from the front
of your vehicle. As the vehicle is accelerated past 8 mph, the front view will automatically
deactivate and the radio view will return to standard radio/map displays. This will occur
each time the vehicle slows to below 8 mph for automatic help when parking or
maneuvering in close quarters. If you wish to manually turn off the front camera view
while it is on the screen, simply press the MUTE button on your steering wheel 2x and
wait for 2 audible beeps. The radio will then return to its standard screen view. It will not
return to the front camera view until the vehicle accelerates past 8 mph and then slow
down again.
• Switch 3 UP - When the vehicle is placed in REVERSE, the rear camera is
automatically activated and will view on the front screen. If you wish to view the rear
view camera while in DRIVE, place the radio on AM, FM etc. (anything other than XM).
Then press the window lockout button 4x within 4 seconds. This will activate your rear
view camera and display it even if you are not in REVERSE. To turn off the rear view
camera view, simply press the window lockout button 4x again or press the MUTE
button on your steering wheel 2x and the radio will return automatically to its standard
view. If you have a factory rear view camera, make sure you have connected the BLUE
reverse wire as described in step 7 of the installation process for proper
GMUNLOCKPRO control.
NOTE: Some vehicles with a factory rear view camera, may require a relay to prevent
mixing of front camera signals immediately after switching out of reverse due to the
factory rear system which may continue to leave the rear camera view on for up to 10
seconds, even after you switch to Drive. This will not occur if you use an aftermarket
camera for rear viewing. Please consult the supplied drawings for additional instructions.
• Switch 2 UP - When the vehicle’s LEFT or RIGHT turn signal is activated, the
GMUNLOCKPRO will automatically switch to the appropriate side camera and display
the picture on your radio. The picture will remain during the time that your turn signal is
actively blinking and will automatically turn off when the turn/lane change has completed.
If you wish to turn on either of the side cameras without using the turn signal, the
GMUNLOCKPRO can provide full manual control. Place the radio on XM and then
press the window lockout button 4x within 4 seconds. This will activate the driver side
camera and display the picture on the radio. If you would like to view the right camera
 press the SEEK button on your radio. If you would like to return to the left camera
 press the SEEK on your radio. You can easily switch back and forth between the side
cameras using the SEEK buttons on your radio. To turn off the side camera manual
viewing, press the window lockout button 4x or press the MUTE button 2x.

Installation of the NV_GMUNLOCKPRO
Installing the NV_GMUNLOCKPRO module is very easy, the installation is completely plug and play (other
than the optional blue wire that needs to be cut if you wish to be able to toggle the OEM reverse camera
while you are in motion, this doesn’t apply for aftermarket reverse cameras)
IMPORTANT: The accessory, 12V and ground wires, are for powering auxiliary devices such
as a camera, DVD player etc. The module itself DOES NOT need to have these connected.
Video & Audio Inputs
An important feature of your GMUNLOCKPRO is the ability to easily input video from a backup camera and
two additional audio and video sources (rear, front, baby cam, DVD, video iPOD, ZUNE, etc. or as a video
input for vehicles not equipped with factory DVD play or video AUX input capability) This input is dependent
upon the presence of a factory rear view camera or, the option for factory rear view camera can easily be
turned on at your dealership. If your vehicle is not equipped with a factory rear view camera and you desire
to use the video input provided by the GMUNLOCKPRO harness, programming instruction for your dealer
can be found at the end of this manual.
Switching between these A/V inputs is described in the previous section of this manual.
If you have the factory camera programming enabled, but do not plan to use a rear view camera, the GM
GMUNLOCKPRO can prevent the screen from blanking during reverse operation. Setup the dip switches for
NO REAR VIEW CAMERA PRESENT and your screen will not blank during reverse, even if it has been
updated for reverse camera operation. This allows you to use the video source provided by the
GMUNLOCKPRO for other purposes and not have the screen search for a rear view camera during reverse.
If you have a factory camera or will be adding an aftermarket reverse camera, place the switch in the UP
position to allow the screen to automatically switch to rear camera view while in reverse.
Accessory ignition Switched 12V power (RED)
The switched ignition 12V source (ACC) RED wire, will turn off when the car is turned off. This is useful to
allow the installation of aftermarket accessories (DVD, radar detector, etc) without worrying that they may run
down the vehicle battery when the car is turned off. It may be connected to your aftermarket Bluetooth kit as
an accessory power connection. This output is capable of 2.5 amps.
If the CAM VIDEO FUNCTION is enabled, the ACC power provided by the RED wire in your harness will turn
off while the car is in reverse and for approximately 10 seconds afterward. This allows you to connect
additional cameras, DVD’s, etc. to the provided video connector and not have the video interfere with factory
reverse camera installations. Use the ACC power provided by the GMUNLOCKPRO and your video device
will be powered off during reverse operation.
Aftermarket rear view cameras should be powered by the reverse tail light. Connect the video to the
connector provided by your GMUNLOCKPRO harness and you are ready to go. You could also connect
additional video from a front, baby cam, or any external video source powered by the ACC power connection
provided by the GMUNLOCKPRO without interference using a “Y” harness on the provided video input. Your
secondary video source will turn off while the car is in reverse preventing interference from simultaneous
video signals.
**The action and operation of the ACC and REVERSE power output wires are modified when
switch 2 is UP and the GMUNLOCKPRO is connected to front, side and rear cameras. For proper
operation of multiple cameras which are being powered and controlled by these connections, the
ACC and REVERSE power outputs of the GMUNLOCKPRO should not be used for purposes other
than the intended cameras when in this special multi-camera mode.
