1) The photo looks like it's made of cheap resin. I'm sure it's a mockup at the very most.
2) Explain this one:
Model Number: NW711VT Brief introduction:
7-Inch 15:9 In-Car Headrest VGA TFT LCD Monitor with Touchscreen.
In-Dash mount, motorized
Someone screwed up there.
3) It's supposed to include a modest amplifier. That's a plus, to be certain.
Completely unrelated to the unit and its specs, who thought that Spiderman swinging over the stylized WinXP logo was a good idea? That just looks silly, IMHO. It also wouldn't surprise me if either MS or Marvel took issue with it. Who knows.
Have you looked in the FAQ yet?
How about the Wiki?
