Thread: External monitor on W221

How do I get the video from the comand the rear aftermarket monitors please?

It depends on the year model. You need to refer to the wiring diagram.

The monitors both rely on a control module which interfaces to the screens. The control module then also attaches to the TV tuner and the front COMAND.

There is an early w221 and later w221. They are different in this situation.

So there is no after market unit for this you know of?

Why will you use aftermarket when there is original.

Could it be because of pricedifference and I dont know where to get a wire diagram.
