  • Building USB receiver?

    I have found the infiniti navi control (buttons + joystick) http://autonet.ca/Spotlight/TestDriv...ure15292-S.jpg

    It has a 7 pin connector. What would I need to convert this to usb or serial?

    If this is possible, you probally will have to take the serial route.

    Can you think of any way to figure out what each pin does? Where do they lead to? Is that screen in the pic hooked to this in any way?

    Try hooking up a multimeter (set to condinuity) to each pin and a ground, and pressing each button to see if it jumps. If you can work out some sort of pattern with this, you may be able to use a digitol input card.
    New car means time for a new carputer.

    Planing.

      The screen is not hooked up, it has nothing to do with the buttons.

        Since it looks like it has 11 buttons and 4 or 8 joystick directions it might be binary coded (Power, Ground and 5 Data lines - which would be good for 32 buttons).
        If that's true, you could use the ccStick to wire it up to the USB.

            Measure the 7 pin connector (coming from the car) for supply (+5V or +12V) and ground first. Then apply the voltage needed to those pins on the buttons panel and measure the signals coming from the panel when you press a button.
            Or, if you're not equipped to do so, ask the friendly car dealer near you

              Can't do that... the navi unit didnt come with the car, so i cant do that.

                Well, then you better ask someone who has a wiring diagram for this unit otherwise you may f**k it up by applying unexpected voltages to it.

                  would it say the voltage anywhere on the board?

                    Unlikely. Do you have a photo of the board? If so, post it (top and bottom layer).
