Help with head unit replacement

Hey all,

So I bought a Chinese android head unit that was supposed to be plug and play. I know you get what you pay for and blah blah blah but I figured for $200 why not take a shot, and worst case scenario I just return it to Amazon. So the wiring harness it came with connects mostly fine, but I have 3 plugs left over that don't fit. I can't find anything online to identify what these plugs are for. If I can figure that out then I'll just splice them together manually. I have a 2012 non-JBL, no navigation. Thanks for the help.

 

I do believe the blue is GPS, and the square-ish one is backup camera. The white rectangular one, I’m not sure.

 

I have a chinese unit as well and not all connectors will be used. Plug it in and see if it works.

 

IIRC when I installed mine (Alpine) not all plugs were used

 

Steering wheel controls?

 

Oooooo, yeah, steering wheel controls. I’m poor, I don’t have those, so not familiar.
