Something that I've grown rather upset with in addition to the sync issues between the BT audio and the video is the inability to control anything from the driver seat and getting everything playing on both screens is an ordeal when the little ones are anxious. Yes, I know I can use an app to control the menus on the screen with my phone but without seeing the screens to know what menu I'm on, it's worthless and if I’m in the back looking at the screen, I might as well be controlling it from one of the remote controls. I think I'm going to start tearing into everything and try to figure out a way to build an interface that will be plug and play to route the audio through discrete wiring to the radio and view the screens on the front display so you can see the on-screen menus and then control them as well. Kinda sad how poorly everything is implemented given how much this system cost.
