Hi again, I have stripped down the touchscreen display and it does not have a membrane or ribbon cable!! it has a matrix of led's. They way the led matrix works is you have infrared led's along the top and one side of the bezel (ie x and y directions). These are the transmitter On the opposing side you have infared diodes. these are recievers,each LED/Doide form a single beam!! When you touch the screen you are touching the actual lcd. This breaks a beam in the X and Y directions and gives the system the touch position.
So I propose to fit a membrane over this screen, I have tried it, it works!!!
I propose to use this membrane;

http://car-solutions.com/en/cable-fo...tion-4-pin.phpI will then connect the video interface, I will cut the R,G,B,S wires at the back of the DVD satnav The Head unit end goes to the RGB (OUT) on the video interface
The NAV end end goes to the OEM (in) on the video interface
The Android's RGB out goes to the video interface NAV (in)
The video interface comes with a log cable and switch
On the back of the video interface are dip switches (MODE)
The audio will connect into the car ACM module!
What do you think??
regards
Euan
