Hi all first time posting...

I have a 2006 Sequoia Limited, w/ Factory installed Rear Seat DVD & NAV Head Unit (E7006). My remote no longer turns on the Rear Screen (and yes that with a new battery installed), right now I'm not sure if its the Remote or the Ceiling Unit itself. I also have the IR headsets and according to my kids there was no sound on them (also fresh batteries), the LED light was ON on them, but I dont recall if the RED or the GREEN LED indicated that they were receiving communication with the Ceiling Unit and I dont remember if the signal is only directed toward the back seat, meaning if I have the IR Headsets in the front seat would they receive the signal.

So I have a few questions....

1- Is there any other means of turning on the Rear Screen, say from the NAV Unit. I noticed that on the "Display Screen" there is a button for "REAR SCREEN OFF" but I was hoping that pressing that button would then toggle it to "REAR SCREEN ON" but it does not appear that it does.

2- Does anyone know of a method to add a "switch" to manually turn on the Rear Screen.

3- Is there a way to control the DISC from the NAV Unit, (you know, Play, Select, Pause, Forward, Back, etc...), while the vehicle is in motion, (or even stopped for that matter)

5- Would anyone have a wiring schematic for the Ceiling Unit?

4- and finally, slightly off topic, can I add a backup camera for the NAV Unit?


Thanks in advance for anyone help, I appreciate it.
