Important Notices
Installation of headrest products require careful planning and preparation. Be extremely careful of seats that have airbags
built into them. Keep wiring away from any air bag wiring (usually identified by yellow connectors and yellow wire jackets).
Damage to air bag wiring can result in personal injury to vehicle occupants. If you have any questions regarding wire
routing or installation in a vehicle, please contact Audiovox Technical Support at 1-800-225-6074.
When connecting power and ground in a mobile video installation, insure 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.
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 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.

MM92HR System
The MM92HR system consists of two headrests each with a 9.2" LCD monitor. An additional DVD player (Audiovox AVD400A or MMDV5
or similar) is required in order to view DVD videos on this system. Alternatively, a gaming system can be used as a video input to play
video games. In either case, it is recommended that a video amplifier (such as Audiovox VA100) be used to eliminate video signal
loss which can result in poor picture quality.
In addition, 2-channel wireless IR (Infra-Red) headphones (Audiovox IR2CHS or similar) may be purchased to allow listening to the
system without wired headphones.
Quick Start Guide
1. Turn on the video source (DVD player, game, etc.).
2. Press the Power button on the monitor.
Note: When the DVD player or source is turned on, it will automatically turn on the headrest monitor if the monitor is set to AV1
input.
3. Press the AV button to view the video source. (If there is no video displayed or video source selected, the monitor will turn off.)
a. AV1 source is the DVD player, game, etc.
b. AV2 is the AV2 input on the front of the monitor next to the headphone jack. Use the supplied adapter to input a video
game or other video source.
4. When using the optional wired headphones, plug the headphones into the headphone jack on the front of the unit.
5. When using the optional 2-channel (A/B) wireless headphones, each headphone has an A/B switch on it. The monitor can be
set to broadcast on channel A (2.3MHz/2.8MHz), or channel B (3.2MHz/3.8MHz. (Refer to the Monitor Operation section to set
the Infrared transmitter to either channel A or channel B.)

MM92HR HEADREST INSTALLATION
Installing the headrest monitor(s) is straightforward and requires minimum effort. If you are unsure of the installation process after
reading these instructions, you may want to have this product installed by a professional. To install the headrest monitor, proceed as
follows:
1) Release the existing headrest and pull it straight up until it clears the back of the seat.
2) Note the distance between the steel tubes of the headrest just removed and adjust the
monitor headrest tubes together or apart as shown until they match this dimension.
Note: If internal seatback sleeve diameter is too big, insert the 12mm or 14mm sleeves into the
existing sleeves before installing the monitor headrest assembly.
3) Guide the monitor headrest cable into and through the seat sleeves tubes while inserting the monitor
headrest tubes into the seat sleeves. At the back of the seat, under the seat fabric, grasp the
headrest monitor cable and pull it down, avoiding any twisting or kinks. It may be necessary to cut
fasteners at the bottom of the seat to access the cables.
4) Mate the headrest monitor cable with the monitor cable assembly (AV input and power) as shown below.
5) Route the monitor cable assemblies to the video source (DVD, Game etc.).
6) It is recommended that a video amplifier (Audiovox VA100) be wired in line between the DVD player or game and headrest AV
inputs. This will prevent signal degradation of the video signal.
7) Connect the black wires to a good vehicle ground.
Connect the red wires to an ACC (switched 12VDC) source. Make sure that all power wires are fused.
