Important Notice
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.
Installation of overhead products requires careful planning and preparation. Be
extremely careful when working on a vehicle with side curtain air bags. Do not route
wires near any portion of the side curtain air bag assemblies. This includes any anchor
points in A, B, C or D pillars of the vehicle. Routing wires in these areas or running wires
by the side curtain air bags can prevent the side curtain air bag from fully deploying which
can result in personal injury to vehicle occupants. If you have any questions regarding
wire routing in a vehicle, please contactAudiovox Technical Support at 1-800-225-6074.
When connecting power and ground in a mobile video installation ensure that the ACC
wire is fused at the point where it is connected to the vehicle ACC wiring. Failure to do
so can result in damage to the vehicle if a short circuit develops between the vehicle
connection point and the mobile video product.
Important Note
The ADV38 incorporates three new features:
1) A wireless FM Modulator
2) Snap on Covers with matching Trim Rings (Shale and Pewter).
Select the color that matches the interior trim.
Please be advised that the wireless FM modulator will perform well in most
applications. However, in certain applications the quality of the wireless
signal may be less than optimal, resulting in static or strong local station
bleed thru. If this is the case, an optional relay box is available. The Audiovox part
number is FMDIRB and it plugs into the 1/8" jack located next to the FM antenna on
the side of the chassis. This relay box is installed between the vehicle antenna and
the car radio to provide the best possible FM reception of the DVD player audio.
When the FMDIRB is installed it is recommended that the wireless FM antenna that
is plugged into the printed circuit board next to the 3.5mm jack be unplugged.

VEHICLE PREPARATION:
1) Locate an accessory power source (+12v when key is in the ACC. 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 theADV38 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 INSTALLTHE MONITOR INAPLACE WITHIN THE DRIVER'S VIEW. THIS IS NOTONLY
DANGEROUS, BUT ITISALSO ILLEGALIN MANY STATES.
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) If the trim ring will be used, it may have to be trimmed to fit the contour of the vehicle's
headliner. Refer to the "Trim Ring Installation" section in this manual.
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.
5) Route the wiring harnesses throughout the vehicle as necessary. (Refer to the Wiring Diagrams on
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 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.
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.

TRIM RING INSTALLATION:
Note:
Note:
This page only covers special installation considerations for thick trim ring installation. If the video
monitor is to be installed in a vehicle with the thick trim ring, it may need to be trimmed to fit the contour of
the vehicle Headliner.
The trim rings supplied with this unit are not designed to be trimmed.
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 over tightened, 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 the mounting bracket. First secure the mounting bracket to the cross-
member, then screw the monitor into the mounting bracket. See the drawing in this manual.
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
fill 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 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 trim ring. Trace the
cut to be made around the entire perimeter of the trim ring.
C) Cut the trim ring 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 thickness 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 trim ring can be painted or covered with a material that matches the headliner before
assembling the trim ring to video monitor.
5) The finished trim ring should be attached to the video monitor, then attach the assembly to the roof.
Tape marker to screwdriver.
Starting at your mark for the
lowest point, trace the contour of the roof

1) Make the connections to the vehicle for the 12 pin wiring harness.
2) Connect the 2 pin power harness to vehicle’s electrical system by
tapping into an accessory hot line and a good ground.
Connect the 12 pin power/signal harness to the mating connector
on the video monitor.
4) Connect the 2 pin connector on the power harness to the 2 pin
connector on the power/signal harness.
5) Verify all functions of the system before final mounting of the
finished assembly.
3)
If the optional relay box is P/N FMDIRB installed, it recommended that the antenna for
the FM modulator antenna wire is unplugged. See ADV38 Wiring Diagram (Figure A) for
antenna location.
Extending the wireless antenna beyond its 12 inch length will cause the FM
modulator to exceed FCC limits of wireless transmission. When installing the unit position the
antenna for best reception.
Plug in 12 pin AV Adapter cable when connecting to an external source (i.e. game
controller, etc).

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 system. Positive switched
systems supply voltage to the interior lights to turn on, negative switched systems apply ground to
illuminate the bulbs.
To determine which system you have to 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 vehicle’s
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.
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.
