General 

The MB Advanced Control, control unit (N175) is an interface module that eliminates separation between the base vehicle and the living area.

It networks the components upstream and downstream of the B-pillar while also enabling easy and comfortable operation.

In future, thanks to MBAC, camper vans based on Mercedes-Benz Vans will become networked homes on wheels.

The user controls the MBAC intuitively using the head unit (A26/17), a multimedia system with optional 10.25" display that can be placed anywhere, or using a smartphone or tablet.

The integrated control concept via smartphone/tablet, additional display or head unit is available in different variants.

Code ED5 (Parameterizable special module) is required in addition to code JA3 (Intelligent Body Control) for this. In contrast, the variant with code E4M (MBUX multimedia system with 10.25 inch touchscreen) is optional.

All other equipment can be selected as an option.
