so by the looks of it, it's using the 54pin apim connector as the harness provided is for sync2/3 not for sync1. it needs a 12pin connector as that's where the signals are for steering wheel controls.
I can see it also wants HS-CAN which is located on the 54pin apim connector and it also wants mm-can which you can get from the 12pin connector.
if you can return it, i would suggest returning it as i have bad experience with xtrons and they're overpriced/underpowered and out of date.
the android stereo i recommend these days is the teyes cc3. if you insist on keeping that android stereo, i can make a harness but the issue is i don't have the 12pin connector in stock and i'm away all of june.
the teyes cc3 provides both harnesses, so you don't need to worry about wiring
