I just picked up my 22 with the REC. No DVD player and I can’t control the back screen output from the giant-a$$ screen. My three and six year old can’t navigate the fireTV remotes and I also can’t get them to mirror.
I called Amazon and they said that the 22 exp and the Lincoln Navigator are the only ones with the FireTV REC that don’t allow control from the front screen panel. I also found out that since FireTVs are not iOS, I can’t mirror my iPhone to them. The audio for the tablets won’t sync with the car system so you have to wear headphones to hear it. They provided 2 pairs, but it seats 6 people back there. I tried to pair my own BT headphones with it and it only allowed me to pair one device per screen. So 3 of my kids have to watch the show in silence. I guess I can turn on subtitles and count that as their reading.
I’m with you, give me a DVD player and access to control it from the front. We also live in the BFE and don’t have cellular service sometimes, so the wifi/streaming doesn’t work and I have to crawl back there to figure it out and restart it for my younger kids. First world problems, but if we pay this much for a vehicle I want it to work!
