Hello!
I want to install Android head unit on my i30 that comes with factory navigation. I did a lot of research, I found pinout diagrams, I even found how to make 12V to 6V adapter to keep the OEM rear camera.

My goal is to make everyting as easy to install as possible, by preparing the needed cables myself and also keep as much of stock functionalities as possible. I imagine I'll end up with something like this. (source).

There are a few things I couldn't quite figure out however, I'll probably make another post about them, for this one I want to understand what to do with the steering wheel controls.

The aftermaket unit I plan to buy is Teyes CC3 2K and here is the wiring diagram

Here is the pinout of navigation unit

I see that there are a few canbus boxes listed, does that mean I need to get one of them for SWC to work? Also I see that on socket C, pins 7 and 8 are related to canbus.

On car/nav side we can see that A1/A2, A13/A14, (MM_CAN_L, MM_CAN_H, HS_CAN_L, HS_CAN_H) are also realated to canbus, but are they related in any way to C7 and C8 on teyes unit? There are also A5 and A17 related to SWC.

Also I see that on Teyes unit, socket G pins 6 and 7 are related to SWC, but still no idea how.

I also know that universal SWC adapters/interfaces like this connects2 exist, but not sure if I need one and how does it connect with everything else.

Any clarifications are appreciated.
