Steering Wheel "Phone Button" Wiring
Hello to all,
First with all my respect to brilliant DIY guys here. I have a 2011 E90 316i Sedan with BMW Professional Audio. No iDrive, No Bluetooth, No Sport Wheel, No Cruise Control, No Seat Heaters. I have a 3rd party Bluetooth Car Kit (Belkin CarAudio Aux) which I love it. It is a simple "Lighter Powered Bluetooth Aux-in" car-kit. It has it's onboard MICROPHONE and a button for some functions like hang-up, play,pause etc. What I want to do is; to connect the PHONE button (which is located at the bottom- right on the left side of the steering wheel) to Belkin's Button. I soldered all necessary wires and extended bluetooth's main module which allows me to control with an external switch. All functions work like a charm. Also I installed the module into the front-dome to place the MIC into the right place. There's no problem up to here. I took the airbag and Steering Wheel trim off and got into the circuit-board. It was too hard for me to figure out this digital signal flow so I found another way. Now I have two wires attached to my PHONE button on my SteeringWheel. And when I connect the main module's switch to these wires, I can fully control the module. Everything works fine. Also all other multifunction buttons on the steering wheel are working to. So, wires that I prepare are on the Steering Wheel side. The point where I get stuck is getting these two wires after the COIL SPRING connections. I have 6-PIN socket in the Steering Wheel, 4th and 6th pins are empty. (Photo Credit: 1AddictsAnonymous) And There are two sockets one with 6PIN and one with 12PIN, after the COIL SPRING. Which pins should I have to connect to get the signal? Without affecting any other system functions also. Thanks in advance. |

Tested On The wheel Side pin connector's 1st, 2nd and 3rd pins With -> On The After Coil Spring Side 1. I tried The 6pin connector but no matching wires between them. I tested with multimeter, no beep except GND. 2. I tried The 12pin one and then I can Get beeps some of them but they are not in order, (pin1 is not Matching pin1) I am going to test all wires in detail to figure out which of them matches each other. Is there any other harness / socket on The after Coil Spring Side, except The ones I mentioned above that I should look for? |

Did you ever figure out what wires are what? I'm trying to install a joycon adapter so I can use the steering wheel controls on my tablet but I'm not sure which ones to use. One would assume that the 6 pin adapter on the steering side would matched to the 6 pin coming out of clock spring.
