2013~2016 CX5 2015 Original Head Unit Interface

[lnguy193]

Hello everyone,
I just pulled out my original radio head unit (as pictured). While I know the wiring interface for the speakers and steering wheels, there are two other interfaces that I am not clear about. I already did some searches but did not find any useful information. Can some one please explain what are these interfaces used for? I know either one is for the USB AUX jack at the armrest console.
Thanks in advance

I'm not sure, just guessing, but the red one should be the gps antenna and the blue is the radio antenna?
It's been like 6 years ago, when I have done work back there.

Thanks! I just figured out the red one is the USB at the center console. The blue one is the radio. I'm still trying to figure out the yellow one. May be AUX?
