Thread: Steering Wheel Controls

You could also use the joystick buttons connected directly to the momentary buttons you want to use and the standard girder joystick plugin will do what you need. If it's USB you'll get more buttons out of it. If it's the joystick port, I think it's limited to 4 unless you use a combination of inputs and diodes.

OK, jumping in here at the end (and at the deep end), I would certainly like to preserve my steering wheel controls when I build the in car computer, however I haven't done circuits and just can't get my head around the diagram god of cpu has done.

If 5v is supplied by the gameport, what is the power node doing and where is it coming from? Where the nodes (the red dots) join, how is this done physically? Would you do so by soldering onto a PCB or by simple joining and soldering of wires?

See, I'm a noob extraordinaire!

can anyone post the SWC.zip file if any of you haveit???? please...........

The file is too big to post on here. Its still on my filebox at https://filebox.vt.edu/users/cholbroo/SWC.zip if your having trouble try again later.

Your probably just making this more complicated then it is... The hardest part should be figuring out which lines you need to tap into on your car. To connect them I just twisted the wire around the diodes and resistors then soldered them together, you really don't need a PCB, but you can use one. Theres a picture on the g35driver site that I posted that shows my completed wire.

You need to splice into 3 lines that your steering wheel controls use. One I call power, (it may actually be a ground in your car as it is in mine when it is connected to the head unit), One is remote control B, and the other is Remote Control A. The line called power does not supply any power, it recieves it from the joystick port.

If you want to retain use of your steering wheel controls with your stock headunit, you should look at my other circuit diagram with the relays in it.

Cheers for clearing that up, I would not want to go down the relay road, no I know power is ground, all is clear

What can I do with my 2004 Acura TL =) I have the wiring scanned I guess should be pretty easy, I just gotta give it a try.
Any thoughts CPU GOD?

Green(1) is the signal and Brown (2)is the Ground.

Here is my diagram...


I only have 1 wire and 1 ground from the steering remote buttons and total of 5 buttons. Do i have to connect to pin 6 on the joystick port for the extra button or would connecting to just pin 3 work ok?

If this works I'll owe you big time for all your excellent work =) I almost went and bought PacAudio SWI-X.

I'm not quite sure on how things are working in your car. Your best bet is to just go try a few things and post results. Your current diagram seems like a good place to start. To know if you have to hook up pin 6 of the joystick, connect your voltmeter to the two lines your currently planning on hooking up and see what happens to the resistance values when you hit the extra button, if it doesn't change, you'll ahve to add it to its own axis.

Do I have to hook up the 5V power source to test this?
