Update:
Installation went really good. Android Auto works very well, sound output is better than factory, SWC controls worked (except call pickup / reject / voice) . I reprogrammed SWC long press for Track next and previous as "Call Pickup" and "Voice" respectively. When I get a call, I could just press "Next Track" for 2 seconds and pick up!

Did you manage to retain any of the cameras with this setup?

Yes. Reverse camera still shows up in the iMid display like before on engaging reverse gear. My car did not have any other cameras.
On the new head unit, I did not connect reverse output wire and the camera input.

iMid options like setting up time still works using steering wheel buttons.

Oh okay, so it likely wouldn't work for my 2016, since my reverse camera and lane watch camera only shows up on the main radio, not the iMid display.
