Had my headrest monitors installed today. I also had a motion bypass installed so the video/NAV could be used up front while the car is in motion. That part of the install isn't working correctly but hopefully we can figure that out with some follow-up with tech support. I am able to play DVD's off the 430N and the video plays on the rear screens in motion just not on the front.
The monitors have great video quality and look very "OEM"ish. They have a black rubbery coating on them that matches well with the leather interior. The mounting system is very sturdy and I have no doubts they will hold up. The wiring for the monitor is routed through the seats.
I don't like the idea of overhead monitors due to how they block the view out the back window as well as how the rear passengers have to kink their necks up to view them. After a lot of research, these were the best ones I could find that fit all the qualities I was looking for. The ones they make for the Mercedes are huge and bulky and look tacky imho.
Here's furthe info on the monitors...
