The android system will work with any controller u like provided u tell the seller what u got .. however you will still need coding if u choose to upgrade the controller because the android system does not replace the idrive system.. it’s add-on.. so you will be left out of the ccc

P.S. the android will take commands from the controller via the CAN system .. so I believe it won’t work with the new controller unless you code it to your CCC.
So their stick with the old controller .. or code the new one before adding the android screen.
