8 Installing the AV7950H headrests

You will need to install the AV7950H headrests and route the cables through the seat backs. The following

steps will guide you through this process.

Step 1: Check the headrest down tubes in the seat backs for any

obstructions. Normally the down tubes are clear and allow the AV7950H

cables to exit from the bottom of the down tubes.

Step 2: Position the AV7950H headrest so the monitor will be facing the

rear of the vehicle once properly installed. Then drape the cables over the

seat back, being sure that the cables are NOT crossed. Place the headrest

safely on the seat cushion (see figure 6).

Step 3: Attach the cable routing tool to a cable. Slowly feed each cable

routing tool through its corresponding down tube until the ends of the cable

routing tool is visible at the bottom of each seat back. Pull the cable until it

extends out the base of the seat back. Repeat for the second cable.

Step 4: Remove the cable slack until only ½ inch is showing. Insert the

headrest into the down tubes. This step normally takes some moderate

force, and may be eased by using a very light lubricant on the posts. Be

certain to pull lightly on the cables as the headrest is inserted to remove

excess slack.

Step 5: Once the headrest is fully seated in the down position

(see figure 7), place a small service loop (6”-12”) of cable in the seat

back, to allow the headrest to easily adjust up or down.

Step 6: Connect the interface cable to the monitor cable,

ensuring that the cables are matched gray-to-gray and black-

to-black. Properly route the cables to ensure they are secured,

out of sight and unobstructed by moving parts and passengers.

CAUTION!

Use caution when pulling on the cables as some seats may have sharp edges or

objects in the seat back which could damage the cables. Sometimes it is necessary to

remove or partially remove the seat back covering to properly install the cables.

9 Routing the harnesses and making the wiring connections

It is the installer’s responsibility to ensure that the safety equipment in the vehicle is

NOT adversely affected by installation of this system. Ensure that the routing of the

harnesses does NOT obstruct airbags, SRS or other safety devices.

You will need to route the harnesses and make the power connections to the vehicle. The following steps

will guide you through this process.

Step 1: This system requires a minimum of 12V (+) ACC Switched and Ground (-) to operate. The 12V (+)

ACC Switched source must be capable of supplying a minimum of 7A. These can be found at multiple

points in the vehicle. The Ground (-) should be located at a Factory Chassis ground point when possible.

Step 2: Select a location to mount the junction box for the AV7900 units. Normally the junction box is best

located under either the driver or passenger seat. Be sure to locate it so that it will not obstruct any moving

parts in the seat or damaged by the feet of passengers.

Step 3: Route the power harness to the dash area where you have located the 12V (+) ACC connection

point. Be sure to protect the cable from any potential sharp edges which could damage the harness in the

future. To avoid vibration noise, use tape to secure the harness whenever possible.

Step 4: Route the FMT antenna wire (purple) toward the antenna/tuner. (Be sure to separate it

from the power wires and avoid any power seat modules or other vehicle harnesses as these

may induce noise into the FM transmission.)

Step 5: When connecting the power harness, Rosen recommends soldering all connections.When using

T-Tap or crimp connectors, always ensure the connections are made with the proper gauge connectors.

Failure to make a proper connection will result in a system failure in the future.

Step 6: With ACC off, plug all harnesses into the main interface unit. Note: Plug the main power

harness in last.

10 Initial test, reassembly, and pre-delivery re-test
