Need info on 2015 Yukon Denali front screen and rear entertainment system

[Noor Alnahhas]

1. Front dash Screen - where is the software / controller for the front screen running? is it in the screen, part of the ECU or the body control module, or a stand alone one?

2. Rear Screens - do the input connections in the rear center console go to a controller, and then the screens or straight to the screens? If to a controller - where is it located?

Trying to figure out how everything is setup.

Since you started this post Noor, may I add a tag along. I'm trying to determine if I can add icons to my 8" screen? I don't have the "text" button that the brochure shows me? Also looks like I should have many more icons than I have room for? I mean if we can swipe the screens left and right, shouldn't there be icons filling up all that empty space?
