Overview

The GM UNI-CAM adds an additional video input on select GM vehicles equipped with the MyLink (model IOH)
4” and 8” color media screens. Forcing (aftermarket) AUX Video or front camera to display at any time is
activated with wire triggers. Note: NTV-KIT629 is a controller only, it will NOT program the MyLink radio

system for rear camera. If adding a reverse camera to a vehicle without OEM RVC and forced cam/AUX video
input is desired as well, you must purchase NTV-KIT630 (UNI-CAM with built-in programmer).

Known HMI

Locations:

GM UNI-CAM Installation

1. After gaining access to the HMI module, Disconnect the gray, 12-pin plug from the OEM HMI circled

above.

2. Disconnect the black, 16-pin plug from the OEM HMI circled above.

3. Connect the provided UNI-CAM 12-pin & 16-pin (male end) connectors into the HMI plug locations

from steps 1 & 2.

4. Connect the factory 12-pin & 16-pin plugs (previously connected to the HMI) into the provided Plug &

Play T-Harness (female end).

5. NTV-KIT629 Installation (with existing OEM reverse camera):

a. When connecting a front camera (or AUX video source) to a vehicle with an existing OEM

reverse camera, the internal relay on the UNI-CAM board is not used (RCA I/Os from module).

Complete all connections on page 5 (FIG 2) using the included VSW-R (included with KIT629) to
prevent ‘bleed-over’ image (when in front camera mode). This includes the following:

b. Black wire of VSW to chassis ground
c. OUTPUT 3 (from module) to White/Red of VSW
d. RCA connections as shown in diagram (FIG 2)
e. Continue with installation on page 4, step 7.

6. NTV-KIT630 Installation (without existing OEM reverse camera):
a. Adding a single rear camera: power your camera with an ACC source or OUTPUT 1 (especially if

using the forced feature), and connect your camera signal directly to the female RCA (into the
HMI) from the 12-pin gray plug.

b. Adding 2 aftermarket cameras: Instead of connecting camera signal directly to the HMI,

connect the RVC signal to the RCA labeled ‘BACKUP CAM’ at the UNI-CAM module. Connect the
front cam/AUX video to the RCA labeled ‘FRONT CAM’. Connect the (male) ‘VIDEO OUT’ RCA to
the female RCA from the CAM T-Harness (at the HMI). Leave the male RCA on the CAM T­Harness disconnected.

c. If this vehicle is equipped with a 4” screen, connect INPUT 3 (pink) to a CONSTANT 12v source.

d. Continue with installation on step 7 (next page).

Factory GM HMI (Human Machine Interface)

The UNI-CAM kit connects at the OEM
HMI Module. The location of this module
varies by vehicle.

NOTE: If this wire is not connected, the UNI-CAM PRG will program for 8” screen (image will appear zoomed in).

7. Optional: Connect INPUT 1 &/or INPUT 2 to an ACC 12v (+) source through toggles for displaying rear

view camera and front view camera (or AUX video) at any time.

NOTE: the factory GM screen may generate parking guidelines (while in reverse), which can be
turned off in the OEM settings (through radio). This is usually required when using the UNI-CAM
for an additional AUX video input (DVD player, etc).

8. Connect the UNI-CAM module to the 18-pin plug located on the Plug & Play T-Harness.

9. KIT630 ONLY: Proceed to UNI-CAM Programming. Note: If vehicle already possesses a rear camera,

this programming step is not needed!
