Installation
1. Disassemble the dashboard and remove the radio. This usually requires pulling panels
and removing screws. Disconnect any harnesses from the radio and screen and
set them aside.
2. From the provided MAS-GT Power harness, connect the following wires to the
car:
3. Connect the provided LVDS cable from the main MAS-GT
interface (port ‘LVDS OUT’) to the MAS-GT Sub
interface (port ‘LVDS IN’). Connect the silver ground
terminal on each end of this cable to the screw closest to
each port (on each interface).
4. From the car’s media screen, find the factory harness with a
keyed, 10-pin plug that will fit in the port pictured below (step 5).
5. Plug this connector into the MAS-GT Sub interface port labeled ‘OEM LVDS INPUT’.
6. Use the provided LCD Cable and connect the white
connector to the MAS-GT Sub interface port labeled

7. Connect the AV Input cable to the port on the MAS-GT interface labeled ‘AV IN/OUT’. If
you’re only connecting a reverse camera (and no other
inputs), the signal input from the camera must connect
to the RCA labeled ‘REAR-C’. Refer to the dip-
switch settings chart to skip/enable AV sources
upon toggle switch presses (Optional. Page 2).
a. If you’re installing a Nav-TV CAM 6 or
Handle Cam along with this interface,
the power connector plugs directly
into the MAS-GT interface port
labeled ‘R-CAM’ for power.
b. Note: The MAS-GT interface will not activate rear-cam with the CAN connection.
You must select the activation as ‘LAMP’ under the menu settings: ’UTIL --> Rear
Select’ section. Refer to step (8a.) to adjust this.
8. Connect the remote eye to the port labeled ‘IR’ and mount it in
clear view of the driver (often it can be stuck inside a vent). This
connection would be necessary if you want to be able to adjust
anything from the MAS-GT interface’s menu.
a. While in any AV mode other than factory (on the display
screen), press the MENU button for MENU 1 , or hold the
left arrow to enter MENU 2.
b. To switch between AV modes, press the ‘OK’ button.
9. Optional: Connect the provided momentary toggle switch to the
port on the MAS-GT interface labeled ‘MODE S/W’(in the power
harness). Pressing this switch with the ignition on will cycle
through any enabled screen modes.
10. Connect the MAS-GT Power harness to the interface at the
port labeled ‘POWER’. Start the car and test for proper functionality before
replacing dash pieces.
11. Note: All other included harnesses not mentioned in this manual are not needed for most
installations. If you would like to know more about the full capability of this interface,
contact NAV-TV tech support at 561-955-9770. Additional features not mentioned in this
manual are not supported by NAV-TV at this time.

FAQs
Q. I cannot switch A/V sources.
A. Check IR or toggle switch connection. Check the LEDs on the interface, if nothing is lit
up with vehicle ignition, check power/ground connections.
Q. All I see on the display is a black screen (no factory image pass-through).
A. Make sure the video cables (IN/OUT) are connected at the proper location
(Screen/Radio/NAV DRIVE).
B. Make sure the video cables are seated all the way.
C. Make sure Dip Switches 5 & 6 are set correctly (resolution or screen size).
Q. Displayed image color is not proper (too dim or color seems wrong).
A. Try to select ‘INITIAL’ in OSD menu.
Q. Rear camera image does NOT appear.
A. Make certain Dip Switch #7 in set down for aftermarket camera, or up for a factory
camera.
B. Try swapping the CAN connection wires. This will not do damage, if it is hooked up
wrong it will only not work.
C. Make certain the camera is properly powered. Check voltage at the camera itself.
D. Try an alternative video source, don’t assume the power/ground is correct unless
you’ve checked it with a multi-meter!
E. If this is a CAN-connected module and you’ve connected the CAN wires, try using the
gray wire (not all interfaces have this wire!) instead of the CAN connection for reverse
activation. You’ll also need to change the Rear Select option in the Menu of Factory (MENU 2)
under UTIL or PARK. Refer to the Menu Adjustments section.
Q. Unwanted A/V mode is displayed upon a toggle press (A/V source switching order:
OEM->RGB->AV1->AV2->AV3->OEM).
A. Check DIP Switch Setting. Refer to page 2.
