Some pictures of the Vizualogic headrests installed in my LS460. These are the A-1250, 7" LCD/DVD player combo. Each screen has a built-in DVD player. Each screen can view it's own DVD, the other screen's DVD, an aux input from a front-panel jack, or an aux input into the junction box that the 2 screens plug into.
It should be possible to feed video from the head unit to the AUX input, but I haven't tried it yet.
Ratcheting tilt mechanism allows the screen to remain vertical even while seat is tilted back.
It may not be easy to see from the pictures, but the color match and stitching match is excellent. Obviously the shape of the headrest, at least in the rear, is not the same as the factory version since the rear surface must be flat to accommodate the vizualogic screen.

Wires are concealed inside of the headrest posts.

I did the install myself. It isn't completed yet because I need to have some TSIBs done that will involve removing the center console, electronics stack, and seats. So I'm going to hold off until those are done so I don't have to have the Lexus techs dealing with my add-on.
So far the system seems to work fine.
It appears that there is an extra video out from the head unit that is used for the exec package screen. I haven't verified that there's a signal there yet but I would be surprised if there isn't. Again, waiting to get the TSIB work done before digging in to deep.

The wiring diagram shows a video output from the radio receiver assembly to the rear seat entertainment ECU. Not sure if these wires are in every vehicle or if the harness is different when there is a rear seat entertainment system.
So it looks like a video output is available, it's a question of whether the wires are already in place. The connector is L56 on the radio, an 8-pin connector that also provides the video signal to the nav screen.
Pin 5 is NTRO which I am assuming means NTSC REAR OUT, 6 is ground, 7 is shield. I would suspect that this video signal is present regardless of whether the vehicle is in motion or not, since it's intended for rear seat viewing.
It should be pretty easy to hang a video monitor on those pins and see if there is a signal there.
I will be installing a set of vizualogic DVD headrests in my '07 next week. I was more interested in finding a way to put an external video signal into the front screen, but it will be a good time to do some experimenting.

It's been 6 years since someone posted in this thread, and Jim hasn't logged in since 2011, so I wouldn't wait for him to answer. Someone else may know though
