Hi Everyone,
I recently got a z4 after years of wanting one, and I am LOVING the car!
The one thing I never liked: BMW's infotainment system.

My car has iDrive so it came with the screen and iDrive knob, etc.
I promptly replaced that with an Android headunit, however, I am very limited as to what I can do with the idrive knob because certain buttons, etc are just not functional through the headunit.

My idea to solve this is:

1- remove iDrive radio and replace it with the non-idrive BMW professional radio.
2- take out iDrive knob and modify it so that it sends keyboard commands over USB
3- plug in modified idrive knob through USB into Android headunit and map the keyboard commands to functions.

I've never had a BMW before, and I've come to find out these systems are extremely intertwined, so I wanted to make sure downgrading to the BMW professional radio is feasible.

And a bonus question:
Has anyone adapted the steering wheel controls for usage with an aftermarket headunit?

Thank you all!
