Yes. That's how the touckscreen overlay works.

How accurate are they?

As accurate as any commercial touchscreen. The touchkit is identical to what the touchscreen manufacturers use for their products.

They all work pretty much the same. There is a difference between resistive and capacitive but a capacitive touchscreen for the car is not very common. Get the resistive one. I've had both 4 wire and 5 wire and don't see the difference. 5 wire is supposed to be "better" but both work identically.

If i understand OP correctly - that won't work! If he/she is trying to control a computer, how is he going to display the computer's output on the screen. If he just want to put a touch overlay on the factory screen to control IT, then what is the touch overlay going to send signals to?

I'm confused by the answers given so far; the way i see it, it won't work at all.

Good point. He'll need to purchase an interface that allows the PC output (which will most likely need to be in video format) to be shown on the car's screen.

You could get a VGA to NTSC converter, but keep in mind the image is going to be hard to read/not very good quality. That's the nature of trying to display a computer image on a non VGA screen.
