DO NOT GET THE REAR ENTERTAINMENT SYSTEM!!! It is a complete waste of money. You can only connect (2) headsets to the system. Our 2015 allowed you to connect (4), so why GM decided to downgrade the connectivity I don't know, but now I have (2) kids unable to listen to what is being played on the screens. Plus it only comes loaded with Hulu & YouTube and you can't add Apps. You have to use a FireStick plugged into the HDMI. Ford & Jeep are lightyears ahead on the RSE compared to GM. It's dumb how my Denali will drive itself and change lanes, but can't connect more than (2) headphones to a (2) screen RSE.
