I need to configure an interface Joycon with the steering wheel of a Fiat 500 made in 2009.
The commands travel through the CANbus protocol, to retrieve the resistive comand I installed steering wheel controls recovery interface by Phonocar (http://www.phonocar.it/it/comandi-al...bus/4-073.html), which returns the resistive comand on the purple wire.
How do I configure it? I need to recover the volume buttons and change the song/track.
I need to install a resistence? what value should be (ohms)?.
