I'm not sure if you can get the options enabled in all honesty. However things like Apple CarPlay, full screen CarPlay etc have been possible.
ACC and stop start are listed as available to do via software update and pay the £750 or whatever BMW charge. Lots of other options available as well, depending what equipment your car came with in the first place. Eg the recorder is available as an option but only if your car came with the 4 cameras in the first place.
