In order to control them from the front, you have to have the headrests WiFi connected to your phone, have your phone plugged into the USB port and then you have to turn off CarPlay to enable mobile app to use the FordPlay app to try to control what’s going on with the RSE. I say try because it’s like having a remote control for a TV you can’t see. You can hit play and pause and fast forward and screen A or B but the vast majority of the time, it’s not doing what you want so you have to pull over and stop, get out and make whatever changes are needed right from the display. If you could disable every single source but the DVD drive or every source but the HDMI, make it 100% of the time either always turn back on or remain off after the vehicle has been turned off, it would be a good start for road trips but as it is now, I’d trade it for an aftermarket setup in a heartbeat. My kids are 3 and 2 so that might change as they get old enough to actually control it by themselves but then I’ll be dealing with them having remote control fights and changing what the other is watching. That said, thank you Lord for these first-world problems because we could all have it so much worse off.
