I have an X910BT hooked up in my truck with 2 headrest monitors for the kids in the back. I can play DVD's over the rear monitors without an issue. Is there any way when I play movies from my SD card that I can make it output to the rear monitors as well? Currently only the DVD will play on the monitors, all other inputs only play on the main screen.

Thanks

nope, that is just the way that they where designed

anyone know if the X940BT is the same? <researching before purchasing>

x940 is dual-zone, you can play a dvd on rear video outputs while viewing nav on Head unit. It is only dvd though - video from SD card will not work on dual-zone
