    Kenwood 6029 touch screen external acccess

    Hello All, port20

    Here http://www.mp3car.com/vbulletin/lcd-...en-output.html
    Picture http://www.arion.net/photos/gallery/...5/kenwood2.jpg

    Pink and orange wire are data wires used to send touch screen coordinates from Kenwood 2din units (6029, 7029) to Nav modules.

    Reportedly, there are people who successfully fed that coordinate signals by unknown mean (controller, interface cable?) into carputer.

    Can you please put some light on the solution, I've been totally out of sync with some unrelated business for few month - Kenwood head looks quite well built and exceptional quality not like other devices

    tonight I got a Kenwood nav cable witch I promptly cut up
    here's what I learned so far

    blue = +5v power up signal
    gray = seems to be same as blue
    purple = +5v nav turn on signal
    orange & pink wires seem to be data they spike to .2 volts DC when the screen is touched I need to do some testing with an O scope to be sure there are two gray sheilded cables inside the nav cable the small one has 2 wires in side

    white = I think is audio left +
    red = I think is audio right +
    sheild = ground

    the bigger shielded cable is the RGB signal cable

    yellow = green
    white = blue
    red = red
    green = Fh
    shield = ground for all signals
    compatable Fh = 60hz only
    tested at 640x480 32 bit true color 60hz

    Fellas, those with experience -
    do you think it is practical to figure out this touchscreen protocol on 2 data wires orange & pink wires seem to be data they spike to .2 volts DC, as reported by port20 ?

    Can it be just a binary X,Y coordinate code that sent over 2 wires ? What are the standards for it?
