    alright, I have a two wire instead of one. I call ed the dealership this morning and confirmed that there are two wire. One input and one ground( green/red +, brown -) I already know that the green/red wire is 3.9v when I test w/ multimeter. I just have to check the brown one this morning to see what directions to take next.

    Check the Voltage between using the red and green as the possitive and using the brown as the negative and post them here. Check with the multimeter set to 20vDC. I would also check check them in OHMs too. I dont want to confuse you but, most likely all hondas will be the same and according to everything i have read, i have resistance rather than voltage.

    Test ONLY with those two wires. MMRed to Green/Red.... MMBlack to Brown. Post values tested in 20VDC and then also in OHMs.

    Let us know...

    the guy at honda told me that the brown wire is the ground, and it like the same as any ground point on the car. also what year is ur civic SI? He also said the radio on the civic's and accord are different, more powerful.

    08 Civic SI... if the ground is the same then you can connect the middle pin of your FB input to a ground source on the chasis. On my car, when measuring resistance, i will only get resistance against the two wires. if i connect the negative to my chasis i will not get any resistance.

    Make sure you have the car on when checking the voltages and off if checking for resistance.

    okay, I just went out to the car and rechecked everything. when the car is off, the green/red wire reads: 9.94 ohm on the multimeter( + probe on the wire and the - probe to body of the car). The I tested both wires together. + probe on the Green/red wire and the - probe on the brown wire. still with the car off, I get 9.94 again. Then when I connect the + probe to the brown wire and the - probe to the body of the car I get 0.00

    Then I turn the car on to get the voltage, and change the setting on the multimeter to dvc( setting 20dvc). Green/red wire to + probe and the - probe to the body, the voltage was 3.9v. then I moved just the - probe from the body of the car to the brown wire, still gave me a voltage of 3.9v . then I hit the buttons on the steering wheel, the voltage would change every time I touched them. so is this finally correct?

    yes... and i have the feeling it's always been correct. if you're getting varying voltages in MDX, then the hardware is setup correctly... you just have to sort out the XML configuration file.

    Agreed. makes sure that when you press the buttons that none of them will go over 5 volt.. also write all of the voltages down for each button press and use those to configure the XML file... your getting closer...

    I new this was right! it has to be the way the file is set up. But I set my file up the way he did in the adboe video, just dont understand why it not working. take a look at the video, I did mine the same way. can I e-mail someone my configuation file, you guys check it?

    No buttons pressed 3.9v when buttons are pressed it never goes over 3.60v for any of the buttons. I also went on and grounded the middle pin on the fusion brain the the body of the car.

    Seems like all connections are fine then.. maybe you can copy and paste your currect XML here and someone can help you out. we can all probably learn from it.
