We just received our 2023 EX with the added rear entertainment system last week. We can not get them to play anything but the dinosaur shows that came pre-programmed on it. I've tried attaching a fire stick and it will pull up but nothing will play. What am I doing wrong? I've tried connecting to the cars wifi and my Iphone wifi and neither work. I see people posting that they can stream shows from a roku or fire stick, but nothing works for me. What are you watching through Roku/Fire Sticks? We leave for a long car trip tomorrow and I need my 3 year old to be able to watch shows to keep him entertained! Help!
