I have a Renault Laugna II - 2002 model.
I have bought a multimedia car stereo (no brand) with universal steering wheel connector.
I would very mutch like to use the original remote stalk in my renault to at least control the volume of my new radio.
The setup menu for configuring the input from remote stalk in the new multimedia player looks like this (marked with a red square); User manual
The wires for connecting the universal steering wheel to the multimedia player are like this (marked with a red square); Schematics
I have not yet tried to connect the original stalk directly because i am worried that i might destroy something;
What is the protocol used for the signaling from the remote stalk to the radio?
What kind of signal is sent out from the remote stalk towards the radio unit?
Is it possible to use the stalk to control my new radio (unnamed brand)?
I hope somone can give me an answer or direct me to someone who can help me.
