So to sum up you can retrofit nbt ebo without expensive emulators and have full functionality. I used a cheap chinese one for 25 pounds and works fine.
You have to make sure you use it between the car can2 wires and nbt plus atm modules as ATM vin number has to match NBT evo.
Also in our cars both microphone wires (if you have telematics module) are in the trunk so you need to wire the left mic to the nbt unit then another set of wires from nbt unit back to ATM module. Also ATM needs 2 wires to nbt for ethernet and can2 from emulator.
My biggest problem was the kafas1 module that was not working as the data are not compatible with latest evo i-level. So lane deviation and FLA was working but not 8TH sign recognition.
I bought a used kafas2 ecu and camera for around 80 pounds and put it temporary on my car but then the camera wouldnt fit on the windscreen. So I modified kafas2 camera so it could fit inside the housing of Kafas1 camera without changing angles etc. Now it sits perfect on my windscreen and I can adjust the angle as well. I can also revert back to kafas1 camera if I want as I didnt modify the housing.
Then I had the problem of vin mismatch so it rejected the FCS codes for sign recognition human detection and FCW. Anytime I was reloading them (you can find the repair set and instructions on youtube in a zip file) it was working fine but after restarting my car it was rejecting it. After some research I found that newer firmware had this feature of FSC rejection if VIN mismatch.
So I downgraded firmware on kafas ecu to a version from 2016(v.59.3_PSdZData_Full) (cadf, bootloader software) and coded the unit again. After finishing the calibration process the car was ready! No more FSC rejection. I have the files if someone want to copy them on his PSdZdata folder to save download time. Then you need to modify the SVT xml files to downgrade the module.

Also as I wanted to avoid messing with my ZGW module in case I wanted to revert back (my car has a lot of options so it needs a high version) I bought an 8SK ZGW without MOST and changed the vin to my car one. Then opened the same FLEXRAY ports as my old unit and the car was ready.

Now everything works and even connected drive. I registered the atm to my bmw account so I can unlock/lock/start ventilation/headlights remotely and also track it on map. For that to work when the car goes to sleep you need to provide emulator with always ON 12V as otherwise it goes to sleep and stops sending CAN msgs to the car from the ATM module. Just make sure your emulator is not drawing a lot of power in standby as it will drain the battery after some days or weeks.

So in total this has costed me around 400 pounds after selling the old set so in my opinion its worth it as it transforms the car and the new display made from glass is match better looking.
In your case, did you plug in the nbt with custom wiring? Can’t find a diy on how to make custom wiring coming from cic to nbt. Not even easy to find a retrofit it. I’m wondering if I could plug the nbt unit straight into my pre lci f10. Thanks for reading. Help is appreciated.
