My E has splitview option. Came with remote and headphones. How do I get the splitview to work so the passenger can watch a movie while moving? I've tried everything but clearly am missing something.

 

SPLITVIEW allows you to simultaneously use different COMAND functions on the front-passenger side and on the driver's side. Different content is seen depending on your perspective when viewing the display.The "Navi" function, for example, can be used from the driver's side while a video is watched from the front-passenger side.SPLITVIEW is operated with the remote control from the front-passenger side.
To do so, use the special radio headphones. Using the headphones on the correct sides ensures an optimal sound. You can connect your own headphones to a special headphones jack. You can use the remote control to operate them.
