HMI ports?

[Swagfu]

I have searched the web and here and came up empty. Can someone tell me which each port on the HMI module does? I know the blue is navigation, but there is also green and black. Does anyone know what those two do? Thanks in advance.

Thank you for the response, but I am not sure what I am even reading...lol. I found out the green port is for a USB in the glove box. Now I am just looking to see what the black port supports. I do have GPS. I drive a 2014 LTZ also and added the console recently.
