Hey, I just bought my 2021 Telluride SX Prestige Dark Moss Nightfall edition with Dune Brown leather seats and Rear Entertainment System. At first, I was a bit put off by the RES. I thought I had made a BIG Mistake. Now, I am in love with the RES. I can connect my Apple TV and Fire-stick into the monitors. I can stream movies, YouTube, Netflix, Disney, Amazon prime, and PLUTO TV to watch regular TV. I use my phone as a hotspot to get connected online. My daughter loves having “TV’s” in the car. I was able to neatly stuck away the cords. Use the house plug in car for power. It’s better than having a clunky DVD in the car any day.
