Audiovox AVXMTGHR1M - Manual (Page 6)

VEHICLE PREPARATION
AVXMTGHR1M 6
1) Decide on the system configuration and the options that will be installed.
2) Read the manuals and get familiar with the electrical requirements and
connections.
3) Decide on the mounting locations and methods of mounting the products that
will be connected to the AVXMTGHR1M.
4) 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. The mounting method, and the location will vary from vehicle to
vehicle, so this manual will only focus for the installation of the AVXMTGHR1M
Monitors in the supplied configuration. The best location for the AVXMTGHR1M
System components is:
a. Monitors: Vehicle specific Headrest NOTE: The Master Monitor should be
installed in the passenger position most used.)
5) 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), a constant power source (+12VDC) at all times,
regardless of the ignition key and a good ground. Generally, these wires can be
found at the ignition switch or fusebox.
NOTE: Ensure that both the constant and accessory power is fused at the source.
Failure to do so may result in vehicle wiring damage.
6) Run the wiring harnesses throughout the vehicle as necessary. (Refer to the Wiring
Diagrams on page 7, 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 seat
movement.
7) Remove all the A/V system components from their packaging and then place
them in the vehicle at their respective locations.
8) Install the headrests:
a. Remove vehicle's original headrests.
b. insert appropriate support tube adaptors in vehicle post guides. (if needed)
c. Hold the headrest above the seat and insert the two cables into the vehicle
support guides Make sure that the headrest is in the correct position (Display
facing the rear).
d. Route the cables through the seat back and out the bottom of the seat while
pulling the cables to remove the slack. Be sure to leave enough slack in the
monitor cables to allow the headrest to move up or down.
9) Connect all the components together (electrically) and verify proper operation of all
the system functions.
