Screen Removal and Interface Installation (GM Truck)
THIS INTERFACE INSTALLS AT THE SCREEN, NOT AT THE HMI UNIT!
1. Remove the trim surrounding the main media
screen using plastic tools and set it aside.
2. Remove (4x) 7mm screws securing the screen
assembly to the sub-dash. Disconnect all
connectors and set the screen aside.
3. The (2x) main connectors used for this integration
kit are shown here (pictured right):
4. Locate the OEM plugs disconnected (from step 3)
previously connected to the screen indicated
here, and connect the provided Chevy/GM T-
Harness or Cadillac T-Harness (only 1 is used per
install) and LVDS Input Cable. The other end of
these cables get connected to the GM-LVDS interface via the provided Power/CAN
Harness and directly to the LVDS IN connector.
5. Connect the provided LVDS Output Cable from
the ‘video out’ connector on the module,
directly to the screen LVDS Video port (shown
above). Make certain the connector is seated
firmly.
6. Make the remaining connections to the module:
a. Power/CAN connection
b. 7-pin touch-data connector to ‘TOUCH’ connector on module
7. The purple wire on the main power harness outputs 12v (+) when in reverse only
(500mA max) and may be used for (single) camera power.
8. The green wire on the main power harness is used to force the rear cam or AV1 video
input RCA (selectable –through OSD menu. See page 5 for menu options)
9. The clear 4-pin molex connector (from main power harness) is not used.
10. Proceed to GM-LVDS Operation on page 4.

GM-LVDS Operation
After all connections are made and dip switches set properly, start the vehicle. Placing
the vehicle in reverse will show the connected rear camera, with dynamic guidelines
overlaid onto the media screen.
If adding a front camera, this must be
activated in the OSD menu (see page 5)
or by setting DIP SWITCH #2 to ON.
Forcing this camera on at any time is
performed by holding the HOME
button or MENU button on the screen
bezel for 3 seconds. The module will
cycle through video modes in this
order: OEM>NAV>AV1>AV2>OEM, and
will only show inputs that are active.
Additionally, a single press of HOME,
RADIO or MEDIA will bring you back to
the OEM screen immediately. Additionally, setting the REVERSE WIRE to AV1 in the
AUX menu and sending 12v to the green wire will force the AV1 source as well.
If the user wishes for the front camera to be set on a timer (front camera shows after
leaving reverse gear, for preset amount of time), activate this feature in the OSD menu
(see page 5).

GM-LVDS FAQ
1. I’ve installed this interface properly, now I have a black screen all the time.
a. Make certain the IN and OUT LVDS video cables are connected in the proper
location (at the screen and proper direction), and seated fully. The ‘OUT’ cable
should go directly to the screen, and the ‘IN’ cable is really just an extension, and
should be connected from the OEM LVDS cable previously connected to the
screen.
b. This kit connects at the screen and not the HMI unit.
c. Make sure the provided ‘OUT’ connector at the screen is seated fully into the
screen (may need to wiggle it in or even shave some rubber from the connector).
d. Make certain the 5-pin ‘TOUCH’ connector is connected to the ‘TOUCH’ port and
not the ‘RGB IN’ port.
e. Verify the LEDs on the inside of the unit are twinkling with the key on. If not,
check the fuse on the red power line going into the main connector of the unit.
2. I have OEM screen and reverse image, but my touch screen no longer works with this
kit connected.
a. You must connect the 7-pin touch-data cable to the module at the port labeled
‘TOUCH’.
3. Nothing happens when I place the vehicle in reverse –it stays on the OEM screen.
a. Be certain DIP SWITCH #4 is ON (down). This enables the RVC port on the
module.
b. Make sure DIP SWITCH #8 is set properly for the vehicle you’re working on.
4. With this kit connected, the touch screen is not working properly (not exact).
a. Make sure DIP SWITCH #8 is set properly for the vehicle you’re working on.
b. If this is a MALIBU vehicle, you need the MALIBU kit instead of this kit, the touch
data is different than the rest of the compatible GM vehicles.
