Stalk control, Android head unit

Hello,



I'm posting about the problem I'm sure everyone changing a head unit in a modern car runs into.

Stalk controls.



So I have successfully installed a new android 4.4 Head unit (see link)

Was easy enough to install, ISO plugs straight in.



However I have hit a wall with the stalk controls (the volume up and down near the steering wheel)



The android unit has two signal input wires for it, whilst the renault has a yellow multi pin plug which covers stalk control and the display screen.



I have found a wiering diagram for it (from another thread), however, the labels for the wires in question don't make a whole lot of sense.

C1 CCU(*) connector 1 DTA 2 CLK 3 MIRQ 4 n/c 5 Radio ON 6 GND

I'm not sure what is meant by pins 1,2,3 (DTA, CLK, MIRQ)



Any ideas?



cheers.
