Processing factory steering wheel controls

[adrian13007]

Welcome. I have a panel to control the radio from the steering wheel to the factory radio but I wanted to make them into pionner radio control. But the factory cube comes to me only one cable. Can anyone help me?

Company called PAC makes steering wheel control interfaces. You will require a piece known as the SWI-PS. Available at your local car stereo shop or online.

But im from Poland and this part isnt avalible here :(

Perhaps the radio control wiring diagram is available in one of the shop mauals on the 3geez wiki?

if you have ebay, you can order it, it's the swi x steering wheel control, it uses the different resistances from the factory controls and converts them into signals like the factory remote on your radio, it copies the infrared signals from the pioneers remote when you program it

Just order it. As long as they ship internationally, don't sweat it. I ship international all the time now that I've been doing electronics.

this is what you need, it should have detailed instructions, the reason the steering wheel controls only have one wire, is when you push the buttons, each button creates a different resistance between the wire and ground. this reads those and translates it into infrared signals like a remote, in order to be able to use this, the aftermarket radio you choose has to have a remote control Pac SWI x Universal Steering Wheel Radio Control Interface | eBay (http://www.ebay.com/itm/PAC-SWI-X-Universal-Steering-Wheel-Radio-Control-Interface-/181311223046?pt=US_Adapters&hash=item2a36fdb506) ignore the years list on the listing, they probably dont even know these radios had steering wheel controls this far back, but those are pretty universal, if you get one and have any issues I'll help you through it, I'm very familiar with these

Are you trying to homebrew this? If you are, I'd be interested in helping out with more specific issues.

it's pretty straightforward, you hook the input of the box to the wire coming from the wheel controls, then you use the remote control from the radio to program each button on the wheel to a specific function, if the resistance range of the wheel buttons isn't high enough,you add an additional resistor in line with that wire, these cars all use negative triggered buttons. it goes from the output wire through a specific resistor for each button, then the ground is through the horn circuit

Yeah, but with a little added logic, you can add more functions to those buttons.

But yeah, probe it out and you'll know what to connect to where if you don't have the proper adapter. If you don't have a multimeter, go buy something decent. The $50 and $100 shootouts that Dave Jones of EEVBlog put on youtube are great starting points, as is the EEVBlog forum.

I work for a car audio supplier, myself I've added a piece made by idatalink called a maestro-sw. You can take the resistance values and create your own settings. + the bonus of a press and hold feature. It will turn the 3 buttons to 6!

See, just a little bit of logic doubles the number of inputs. I am willing to wager it can be expanded further, using the old cruise control buttons.
