DO NOT PURCHASE THE REAR ENTERAINMENT SYSTEM! It is a waste of money. You can only connect a total of (2) headsets to the system. Our 2015 allowed at least (4), so why GM downgraded with this system on connectivity I don't know. Plus it only has Hulu and YouTube and you can't add Apps. You have to use a FireStick or similar device plugged into the HDMI. Either spend the money on an aftermarket system or just use tablets with the WiFi. Ford & Jeep Rear Enterainment is light years ahead of GM. It's crazy how my Denali with drive itself and change lanes, but can't connect more than (2) headsets to the RSE.
