A short video demonstrating how I got my Renault Twingo’s steering wheel remote buttons working with my JVC head unit using an Arduino Nano to take input from the steering wheel remote and turn it into a signal the JVC radio understands.
I uploaded the code (with lots of comments!) to http://pastebin.com/fXbScxV4.
EDIT 2017-12-18: By popular request I’ve drawn a schematic. It’s available at https://imgur.com/vg5zvh5

Hi there! I want to adapt the code to another car. How do I find out which way the car sends commands?
hi, can you explain how to construct the circuitry via skeches or so?
I'd also appreciate if you could show us the cicuitry more detailed 🙂
Hi! How do you connect optocoupler? Can you draw a schema?
hello my frien, can you send me the circuit or schema to my email ? [email protected]
где купить ?)
Hi Bart,
I'm also interested. I have similiar radio and similar remote. Could you please send me the cabling and the ciruit diagram to 1soproni at gmail dot com?
hi! please send me a wiring diagram to [email protected]. Many thanks!
thank you so mush~
your code wheel problem, solved code in eeprom
#include <EEPROM.h>
void SaveEEPROM(int pin_cycle_current, int pin_cycle_stored)
{
EEPROM.write(0, pin_cycle_current); // write(address, value)
delay(100);
EEPROM.write(1, pin_cycle_stored); // write(address, value)
delay(100);
}
int GetEEPROM(int gubun)
{
int returnvalue = 0;
if(gubun ==0)
{
returnvalue = EEPROM.read(0);
}
else if(gubun ==1)
{
returnvalue = EEPROM.read(1);
}
return returnvalue;
}
if (pin_cycle_current != pin_cycle_stored)
{
if(first_run && ((GetEEPROM(0) == 0 && GetEEPROM(1) == 1) || (GetEEPROM(0) == 0 && GetEEPROM(1) == 2) ))
{
first_run = false;
}
SaveEEPROM(pin_cycle_current, pin_cycle_stored);

Hi! Very nice job! Where did you find jvc headunit's protocol? I cant find anywhere. Thanks. Bye.
I find Renault radio code calculator app with all right.

Hi it is very good job, can you send to me a circuit diagram? [email protected] Thanks 🙂
Hello it is the best project but without wiringdiagram and parts for made it. Can you send to me mail with wiringdiagram and used parts?. I want modify this because i have Blaupunkt Brisbane 230 and there are 3 cable Gnd, SWC 1 and SWC 2. In my blaupunkt Stering via programable resistance (You can programing functions in menu SWC). But i can't Connect directly because in Renault remote control have 6 cable without resistance but it is the tablemap of sig. Thanks shrekos133@gmail.com
