So I recently bought a 2021 Yukon with a rear seat entertainment system. There are 2 HDMI ports as for some reason GM didn't want to include Roku or Fire TV in the system. But to solve this problem and make it look as clean as possible without having to grab and take out a fire stick, I used these rectangular adapters. This should point the stick down so it doesn't stick out and break or get knocked over by incoming children. I connected this using a Fire TV Stick Lite and a RevainBasics USB Type-C to Micro-B 2.0 cable. I've had great success since installing it and the kids love it. Photos coming soon
