1) Read the manuals and get familiar with the electrical requirements and
connections.
2) Prepare the vehicle by removing any interior trim necessary to gain access to the
vehicle's wiring as well as all areas where interconnecting wire harnesses will be
located. (Refer to the Installation Procedure). The mounting method, and the
location will vary from vehicle to vehicle, so this manual will only focus for the
installation of the UNIT Master and Satellite Monitors in the supplied configuration.
The best location for the UNIT components is:
a. Monitors: (NOTE: The MMD7HRM Monitor should be installed where the
passenger usually sits behind the front passenger seat.
b. Audio Interface Box: Under either seat where monitors are located.
VEHICLE PREPARATION:
3) Locate an accessory power source (+12VDC present when the ignition key is in
the accessory and run positions. 0VDC should be present when the ignition key
is in the OFF position), and a good ground. Generally, these wires can be
located at the ignition switch or fusebox.
(NOTE: Ensure that the switched power is fused at the source. Failure to do so
may result in vehicle wiring damage.)
4) Run the wiring harnesses throughout the vehicle as necessary. (Refer to the
Wiring Diagrams on page 10, as well as the wiring instructions for the individual
components and accessory options being installed). Be sure, that all the wiring
is protected from sharp edges and is routed in such a manner that it will not be
pinched, when it is fully installed. Be sure to leave enough slack in the wiring at
each component to allow sufficient working room. Be sure to leave enough
slack in the monitor cables to allow the headrest to move up or down, and the
seat to move backward and forward.
5) Remove all the components from their packaging and then place them in the
vehicle at their respective locations.
6) Install the Headrests:
a. Remove vehicle's original Headrests. Measure the distance between the
posts and adjust the new Headrests to same dimension.
b. Place the appropriate headrest support tube into the support tube hole. (If
needed)
c. Hold the UNIT Headrest above the seat and insert the two cables into the
headrest support tube holes. Make sure that the headrest is in the correct
position (Display facing the rear).
