That type of COMAND-APS (as used in A/B/C/CLK/ML/GL) can not play DVD in the slot.
However, it does have a video input for connecting TV tuner and/or reversing camera (for instance in ML)
Sadly there is no box that pretends to be the TV tuner (like there is for old COMAND)
So, at the moment, you;d have to add the MB TV tuner and use the aux inputs on that
