I really liked iDrive controller, that comes with NBT. So I decided replace my old CIC controller with newer version.
Here is close comparison between them, NBT version looks much nicer:

NBT controller communicates with ZGW thru K-CAN2 line, in order to controller to work, I installed K-CAN2 wires from ZGW module to the NBT controller:

My CIC controller had 10 pin plug, in which also are 360º camera and PDC connections. So there no other way, I had to connect both controllers to my car, otherwise 360º camera and PDC buttons wont work:

After that, I dismantled CIC controller completely and tucked only electronic part under gear selector:


After ZGW firmware update to latest version, no coding was not needed for NBT controller, it started to work right away.
And here is final result

N57 engine has known issue for timing chain stretching out and sometimes even snapping and causing a lot of damage. Recommended change interval for N57/N47 timing chains is max 250 000 km. My car had at least 30 000 km to this mileage, but decided to be safe.
So I bought all the parts needed for this kind of job.
All parts are BMW OE (except oil filter - made by Hengst and injector gasket rings - made by Bosch):

Handed car over to very experienced local guy, who did this job around two days.
I was really glad, that I did not wait anymore with this job, engine timing was already quite off:
