    You need to isolate those buttons or figure out what circuit they are on. There look to be resistors and LEDs inline with those switches will throw everything off. Either figure out what the circuit is, or get rid of it.

    Unless you can verify that the switches mounted on that board are completely disconnected from every component on that board you are going nowhere.
    One of the first things to do when tracing a problem, no matter how simple the circuit, is to eliminate every unknown, that board is an unknown.

    Either find two simple bare switches and try the circuit or remove the wires from the board and leave them disconnected and not touching.

    That is now the state with two switches in the off position, measure the voltage.

    Join the wires that went to one switch together (switch closed) and measure the voltage, disconnect them and do the same test with the other two wires. Now compare the results

    Any update using just wire to wire contact taking the unknown PCB out of the equation?

    Ok so the circuit worked perfectly with the PCB/Buttons out of the equasion. Obviouslly something is going on on the PCB, but I don't have a clue what. At least now I know I have the wiring correct, as long as I can work out what's different with these buttons.

    Bad news though. So cabling live, with bare leads finaly bit me in the arse. My own fault. Had an arm spasim and shorted something out. Now seeing 4.9V on Analogue Input 10 with nothing even connected to the board.

    Any chance you have a v4 kicking round your house Toaster? I can't seem to get one anywhere and with the recent delays to the v6 I'm a wee bit hooped.

    Cheers

    Skitlz I managed to get this working with RcJoyCon including the joystick in the middle. However there are many buttons with the same value which make the buttons equal even when applying resistors. But in the end I can get about 50% of them functioning if not more. For example the joystick, I can use up/down left/right but up and right are the same value even with resistors.

    How can I do this? RCJOYCON has 4 seprate channels you can choose from, if your button on the graphical bar moves on mulitiple lines I activate only one. The only downfall is channel C and D only supports 2 buttons each. A and B support tons, but cant get the resistance to co-operate into a nice neat flow for the buttons.

    Other strange observations is you dont always need positve and negative, or a single resistor seems to work well on the toggle to create a third position or you can reverse polarity and it will change some buttons. I use aligator clips and swich the wires to see the different results.

    RCJoycon is very easy to install, you just push the button it shows the resisitance on a graphical bar, then you drag and drop a key command to that area on the bar. DONE.

    I used 22 gauge (Cat 5 twisted pair)wiring and fed them through that little circular whole in the bottom. Its all closed off now and ready to install. I skipped wiring some buttons because they must be connected also. If I wired a button that was close it supplies enough power to activiate other buttons near by.

    If you find a way to be able to make more of a difference with resistors please share. If I do, I will post as well.

    I checked service manual for the Nav control unit and see where the actual power flows, its not that granular. I may try and power the unit up as opposed to just using the power of the JoyCon and see what the results are, but dont want to damage the Joycon so I will contact the maker and see.

    Anyway im sticking with that and installing. 50% if fine for me this year. Frankly I dont think I would use the 11 buttons anyway. Will look at it next yr or if you can figure the rest out.

    All fine and dandy, but that assumes the circuit you have works and outputs variable voltages. And if the OP gets that working, then everything he has for the FB will work. If he doesn't get that working than any solution whether it be an FB or a joycon, will not work.

    Not really, here are my buttons set up real quick, like I said mine already works, but not all the buttons and if I use the joystick some must be removed and added to C and D channel. I can separate them on the unused channels. I am a Fusion Brain customer as well, I just dont like your support, check these boards on page one, me asking how to use a simple device that YOU SELL but no reply, poor customer service. So I went with a solution that I can communicate with the company an get answers. Anyway back to the topic. My apologies to the OP going off topic for a couple of sentences.

    And as shown in your picture, your wire you are attaching to gives differing voltages for different buttons.

    The OP's current problem is that the "extra" circuitry around his buttons are preventing him from differentiating which button is which. If he attached the same wire to any device, whether it be the FB, a DVM, or the joycon, every button will read the same voltage. Therefore noway to figure out which is which.

    So again, you are just wrong here. To each their own, and glad you have a solution that works. But it is completely irrelevant to this topic as the problem is the input to the device, not the parsing of the input from the device to PC.

    And email is usually the best way to get a hold of a company. If you have a problem or question send an email. I try to check the forums often, but if I miss your new post then it gets buried forever. An email is a sure thing.

    Just wrong? We have the same board, we have the same "extra circuitry". We have the same car 350z, mine is a 2008 his is a 2006. We are working on the same circuit Navigation board from a 350z that we wanted to use with a carputer. We were both working on a solution for the same board. Same buttons same location in the car just below the nav screen. The boards are not different, they are the same. As I keep saying not all buttons are the same voltage, some are, some are not.

    Now, again my solution is not 100% either, notice only 8 buttons not 11, but ill take the 50%-70% solution unless you guys can figure out the rest of it with a FB.

    With a dedicated forum from your exclusive supplier I would have thought this would be a good place to ask my question, the question is still on your the first page, its not like there is a ton of activity here its hardly "buried" , it was posted over a month ago and its only 11 posts down from this one. I also asked the same question as the OP, you asked I post pictures so I posted them, and once again you never replied.

    No worries man, its all good. I still use FB for temps, and I hope you guys solve this!
