I have this:
Panasonic CQ-VD7003U In-dash DVD receiver with 7" video screen at Crutchfield.com (http://www.crutchfield.com/S-7sCwQAitxZX/p_133VD7003/Panasonic-CQ-VD7003U.html)

It has this available:


Power: 16-pin jack for use with supplied display unit wiring harness
Navigation: round 13-pin connector for use with a Panasonic Car Navigation System that will be available in the future
System-up: square 12-pin connector
Front Pre-out: left and right RCA audio jacks
Rear Pre-out: left and right RCA audio jacks
Subwoofer Pre-out: single RCA audio jack
Center Pre-out: single RCA audio jack
A/V Out: left and right RCA audio jacks and an RCA composite video jack
A/V 1 In: left and right RCA audio jacks and an RCA composite video jack
A/V 2 In: left and right RCA audio jacks and an RCA composite video jack
Radio Antenna In: female Motorola jack
Camera In: RCA composite video jack for use with an optional rear view camera

And I would like to hook it up to a computer and use the touch screen like a mouse.
If you think you might know where to start your help would be appreciated.

You will probably need special drivers. I know applications in Windows environments have to be designed to be operated by touch-enabled devices through implementing the support during the development process. AFAIK there is no magic switch that you can flip to swap mouse functionality for touch control.

MSDN link: Working with Input from Touch Screens (http://msdn.microsoft.com/en-us/library/ee526140.aspx)

Edit: Actually, this link (http://msdn.microsoft.com/en-us/library/dd371406%28v=VS.85%29.aspx) claims that it is not absolutely necessary for developers to explicitly enable Touch support in order for it to be used but it does not seem to elaborate on how that access can be configured.

The problem I'm having is that touch screens generally offer some kind of output (usb), but the one I have is in-dash and only has video inputs. Anyway what I was thinking is that there's probably some kind of wiring that goes from the screen to the board that I can tap off of and make a USB output from, then use some usb spy software and try to make a driver for it.

Basically what I'm looking for though is if anyone has done something like this before and knows how to make the cable or has any tips / leads.
