GENERAL INSTALLATION APPROACH:
1) Decide upon system configuration and options that will be installed (i.e.: what components, VCP,
Video Game, external amp, wireless headphones, VCP, 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 components etc.), this should be done now as well.
(Refer to Page 3).
5) Route the wiring harnesses throughout the vehicle as necessary. (Refer to the Wiring Diagrams on
pages 6 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 of each component.
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.
GENERAL SYSTEM CONFIGURATIONS:
Thefollowing is intended toprovide some of thesystem configurations that arepossible with the VOD8521
series Drop Down Video Systems:
-2-
Notes :
There are a few audio output options that can be added as follows:
a) Wireless Headphones (P/N MVIRHS).
b) Wired relay box for wireless FM Modulator.
The VOD8521 video systems are only intended for an overhead, drop down installation. It is not
intended for Seatback or any other type of mounting. The hinging mechanism is designed for
horizontal, drop down use only.

VEHICLE PREPARATION:
1) Locate an accessory power source (+12v when key is in theACC. and run positions, and 0v when
key is off), and also a good ground generally, these wires 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 in-
stalled. The monitor should be located in such a manner that it can be comfortably viewed by rear
seat passengers. NEVER INSTALLTHE MONITOR INAPLACE WITHIN THE DRIVER'S VIEW.
THIS IS NOT ONLY DANGEROUS, BUT ITISALSO ILLEGALIN MANYSTATES.
4) Once the mounting location of the monitor has been determined, there may be additional prepara-
tion 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.
C) If the mini-console will be used, it will have to be trimmed to fit the
contour of the vehicle's headliner. Refer to the "Mini-Console installation" section in
this manual.

MINI CONSOLE INSTALLATION:
This page only covers special installation considerations for the mini-console installation. If the video
monitor is to be installed in a vehicle with the mini console, this console 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 di-
rectly (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 mini-console 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 mini-console 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 (12"x9"x3/4"). First secure the
plywood block to the cross-member, then screw the monitor into the plywood. See the drawing on
page5.
2) It is best to mount the video monitor to the roof structure without the mini-console first. There
shouldbe a gap betweenthe headliner andthe outer flange ofthe video monitor. Themini-console
should be cut to full this gap. Apply masking tape to the outer surface of the mini-console 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 mini-console on the masking tape. Be careful
to consider not only vertical 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 mini-
console.
C) Cut the mini-console using a sharp utility knife or shears. Make the cut in several
passes over the marked line, each time cutting a little deeper. It is not necessary to
cut completely through the plastic, the cut only need be over 50% of the wall thick-
ness of the plastic. By bending the cut back and forth several times, the plastic will
break cleanly at the cut.
D) Check the fit of the trimmed console and make any minor adjustments necessary.
4) The mini-console can be painted or covered with a material that matches the headliner before
assembling the mini-console to video monitor.
5) Thefinished mini-console should be attached to the video monitor, then attachtheassembly to the
roof.

Positive Switched Dome lighting

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 purple / 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 purple / 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 purple / 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.

Troubleshooting:
SYMPTOM:
No power at Video Monitor
Power but no video or
sound
Picture, but no sound
Static on TV Stations
(Tuner Version Only)
No Infrared remote func-
tions for VCP (or other com-
ponents)
REMEDY:
-Verify +12 VDC onRed wire at2 pin Power Harnessbehind video monitor.
Verify ground connection with continuity test from known good ground to
black wire at 2 pin Power Harness
-Verify that the correct source is selected (i.e.: 1,2,3 or 4). Verify that the
sourceison and playingaknown good media (suchas a videotape). Verify
connections at both ends of the source component harness.
-Pushandholdthevolumeupbutton until sound is heard over headphones.
If problem is limited to the dash radio, verify radio is tuned to the correct
channel,and that power to thewired RF modulator is on. (Referto instruc-
tions with modulator kit). Otherwise, verify all connections per the wiring
diagram on page 6.
-Press Auto Program button. Then press CH up or CH down. Verify an-
tenna mounting and connections to the tuner.
Note: Due to the nature of TV signals, vehicle motion, direction the vehicle
is facing, distance from the transmitter, nearby surroundings and weather
may adversely affect TV reception. These conditions may result in the
following: picture roll, "snowy" picture, or momentary loss of color.
-Check batteries in the hand held remote (not included with this kit). Verify
that the IR LED ( page 6 Wiring Diagram) is properly attached to the sen-
sor window of the VCP (or other component).
