All BMWs F01 2010

There was this 2010 F01 that had rear entertainment center with its own DVD player...I coded the front Navi screen for VIM....Question is there any way to make the front play the same DVD movie and vice versa?? It seems as though the DVD player in the rear works independently of the front one and vice versa...We could not get it to play on both the rear screens and the front screen....Anyone know how to get this function working if its possible..This F01 had EVERY single conceivable option equipped with the car...
