IMPORTANT
An LCD panel and/or video monitor may be installed in a motor vehicle and visible to the driver if the LCD panel or video
monitor is used for vehicle information, system control, rear or
side observation or navigation. If the LCD panel or video monitor is used for television reception, video or DVD play, the LCD
panel or video monitor must be installed so that these features
will only function when the vehicle is in ‘park’ or when the
vehicle’s parking brake is applied.
An LCD panel or video monitor used for television reception,
video or DVD play that operates when the vehicle is in gear or
when the parking brake is not applied, must be installed to the
rear of the driver’s seat where it will not be visible, directly or
indirectly, to the operator of the motor vehicle.

GENERAL INSTALLATION APPROACH:
1) Decide upon system configuration and options that will be installed (i.e.: what components, VCP,
Tuner, RF Modulator/external amp, remote headphones, DVD, etc.).
2) Review all manuals to become familiar with electrical requirements and hook ups.
3) Decide upon mounting locations of all components and method of mounting.
4) Prep the vehicle by removing any interior trim necessary to gain access to vehicle's wiring as well as
all areas where interconnecting wire harnesses will need to be located. If any access holes need to
be cut into the vehicle (headliner, other trim component s etc.), this should be done now as well (Refer
to Page 5).
5) Route the wiring harnesses throughout the vehicle as necessary. (Refer to the Wiring Diagrams on
page 8 and 9 of this manual as well as the wiring instructions for the individual components and
accessory options being installed). Be sure that all wiring is protected from sharp edges and is routed
in such a manner that it will not be pinched when all components and interior trim are fully installed.
Be sure to leave enough slack in the wiring at each component to allow working room.
6) Remove all A/V system components from their packaging and place them loosely in the vehicle at
their respective locations.
7) Connect all components together (electrically) and verify proper operation of all system functions.
Note: This is best done BEFORE components have been permanently mounted.
8) After verifying proper operation of the system, proceed to mount each of the components.
9) When all components are mounted, recheck function of entire system again to ensure that no wiring
was pinched or connected improperly during final installation.

VEHICLE PREPARATION:
1) Locate an accessory power source (+12v when key is in the ACC. and run positions, and 0v when key
is off). Generally, this wire can be found at the ignition switch or fuse-box.
2) The mounting method and location will vary from vehicle to vehicle, so this manual will only focus on
the installation of the video monitor and related console accessories.
3) Generally , the best location for the video monitor is where the vehicle's factory dome light is installed.
The monitor should be located in such a manner that it can be comfortably viewed by rear seat
passengers. NEVER INSTALL THE MONITOR IN A PLACE WITHIN THE DRIVER'S VIEW. THIS
IS NOT ONLY DANGEROUS, BUT IT IS ALSO ILLEGAL.
4) Once the mounting location of the monitor has been determined, there may be additional preparation
work necessary, depending on the vehicle structure and installation method. Some of the steps that
may be required are:
A) Removal of the vehicle's dome light
B) The headliner may need to be trimmed using the trim ring as a template per the
drawing below.
C) If the trim ring will be used, it will have to be trimmed to fit the contour of the vehicle's
headliner. Refer to the "Trim Ring installation" section further on in this manual.
Installation Guide
FULL SIZE CONSOLE INSTALLATION
There are several “full size” custom consoles available for selected vehicles. Some of these vehicles are
the Chevrolet Suburban, Ford Expedition, and Dodge Durango. These full size consoles incorporate
several additional features, and are particularly useful if the vehicle you are installing this system into
already has an OEM overhead console in the headliner.
Refer to the installation manual that comes with the console itself for complete installation instructions.

TRIM RING INSTALLATION:
This page only covers special installation considerations for the trim ring installation. If the video monitor
is to be installed with a custom full sized overhead console, refer to page 5.
If the video monitor is to be installed in a vehicle with the trim ring, it may need to be trimmed to fit the
contour of the vehicle headliner.
1) In this installation, the video monitor is mounted directly to the overhead cross-member in the roof
using the mounting screw bosses. These screw bosses should contact the cross-member directly (i.e.: no gap between the screw boss and the roof structure). Also, be sure that the screws
do not pierce the outer roof skin when fully fastened to the cross-member. The trim ring is
attached to the video monitor using the perimeter screw bosses. It is important that the screws
used in this installation are not overtightened, and that the video monitor and trim ring are mounted
in such a way that the assembly does not distort (or bend) when the mounting screws are tightened. An alternate method is to use a piece of plywood (5"x9"x3/4"). First secure the plywood
block to the cross-member, then screw the monitor into the plywood. See the drawing on p age 7.
2) It is best to mount the video monitor to the roof structure without the trim ring first. There should
be a gap between the headliner and the outer flange of the video monitor. The trim ring should be
cut to full this gap. Apply masking tape to the outer surface of the trim ring in the areas where the
cut will be made.
3) Mark the cut to follow the necessary contour of the roof. The suggested method of marking is as
follows:
A) First mark the narrowest point of the trim ring on the masking tape. Be careful to
consider not only left-right location, but fore-aft location.
B) Using the handle of a screwdriver, make a “transfer marking tool”. See diagram
below. Place the tool against the roof and the marker against the masking tape on
the mini-console. Trace the cut to be made around the entire perimeter of the trim
ring.
C) Cut the trim ring using a Dremel Tool.
D) Check the fit of the trim ring and make any minor adjustments necessary.
4) The trim ring can be painted or covered with a material that matches the headliner before assembling the trim ring to the video monitor.
5) The finished trim ring should be attached to the video monitor, then attach the assembly to the
roof.

CONNECTING THE DOME LIGHTS
The dome lights in the video monitor require three connections to the vehicle's wiring. There are two
common types of dome light circuits used, positive or negative switched. Positive systems supply voltage to the interior lights to turn them on, negative switched systems apply ground to illuminate the bulbs.
To determine which system you have you must locate the wires at the dome light. On a positive switched
system, with all the doors closed and the lights out, both wires at the dome light will rest at ground. When
the light is activated, one of these wires will switch to +12 vdc. This is the vehicle's switching wire. On a
negative switched system, with all the doors closed and the lights out, both wires at the dome light will
rest at + 12vdc. When the light is activated, one of these wires will switch to ground. This is the switching
wire.
For positive systems, connect the violet / brown (Lamp auto) wire to the vehicle's switched wire. Then
connect the red / black (lamp on) wire to a fused constant 12 volt source and the black / red (lamp
common) wire to a good ground. Positive systems are commonly found on Ford vehicles.
For negative systems, connect the violet / brown (Lamp auto) wire to the vehicle's switched wire. Then
connect the red / black (lamp on) wire to a good ground and the black / red (lamp common) wire to fused
constant 12 volt source. Negative systems are commonly found on General Motors and import vehicles.
Note:
Some vehicles which incorporate transistorized control of the dome light circuit, such as the 1999
Dodge Caravan, may require that the violet / brown (Lamp auto) wire be connected to the door pin
switch wire, as the additional current draw of the Monitor's lights may not be supported by the output
of the vehicles body control computer.
