General Car stereo connector schematics

[mosfidelity]

I am going to map out the steering wheel controls to control my Nexus 7 tablet that I have changed the original stereo for. Does anyone have the pin-out/schematics for the connector going into the original stereo (not the ISO-connector)? What pins are for the steering wheel controls?

By the way, it's a 2015 Panda Cross.

So you've actually replaced the head unit? Pics, please!

It's actually part of a bigger upgrade. Speakers have been changed, and the whole car has been sound dampened. The Nexus is currently mounted on a temporary wooden fixture in the head unit opening while I finish up so I can 3D-print or mold a real installation that looks good. It's working flawlessly though, with both DAB-radio and Tidal/Spotify. Using RCA for the moment, but when the DSP arrives, it will be digital only (optical).

Yeah, schematics are cool!
