Yea I thought the fact that BMW just released a big software update meant that it would enable Apple maps in the display. The article specifically mentioned BMW, and the functionality would have to apply to iDrive 7 cars since iDrive 8 is running in the cars with the one giant screen (🤢), it should work in my car. The display can definitely do it, it shows 3D navigation for with the built-in Nav. Perhaps, like you said, it requires another update from BMW or perhaps it'll just work in the final 17.4.
