|After Removing from Headrest
I cut the outer liner off.
Then unscrewed the rectangular plastic panel. Then removed the other visible screws. But this was not necessary since all that needed to be done is to press in the finger tips and at the same time lift the monitor away from the box that's holding it. The finger tips are easy to see from the back.
The electrical cable runs down one of the support tubes and the connectors on both ends are too big to go through the tube. So the next step is to disassemble the 4 socket connector on the monitor end of the cable. It can then be reassembled with no soldering, just snap toghther.
The box that's glued to the leather and maybe the rectangular cover will be kept to make a box for the monitor.
You can see the 6 plastic fingers that hold the panel into the box. The bottom center finger is directly below the black square which is the IR remote input.
Notice the wires coming up through the hollow tube and ending in a 4 socket connector. The connector goes into a 10 pin header (J201) so that the red wire is on the pin closest to the center of the monitor. Then DC black, then yellow and finally the black shield for the video.
There are a number of unpopulated locations including a connector at the bottom center of the PCB. The monitor assembly that's held by 4 corner screws could be detached from the bezel holding the control buttons and fitted into a different bezel.
On the right there is a gray plastic insert which is the label 7" TFT Monitor, but I've seen other units with an LED bar graph in that spot.
Although it looks like there are three wires, Red, Black and Yellow, that's not the case. The yellow wire is actually a coax.
