HiFi/Navigation: Fondentertaiment

[emmi]

Hey folk. hope that its okay that i write in English, but german writing isnt that good. ;(

i have a question that i hope some expert in this forum could answer. i own a bmw 740li (f02) with fond entertainment. and was thinking if its possible to view the same think at same time on all three screen just like on a e65/e66. so when putting a dvd in front then persons in back could see the same. its not possible by default.
ps i can se the front dvd title at the back but its grey (not possible to select)
