Im wondering about the same thing. Im kind of green with it comes to coding..
I just purchased and received my new unit. I have a BMW 116D 2012 without nav and bt streaming, only for calls.
The new head unit: 65128792157 - I also have the 6.5 glossy screen and the control unit from the same donor car (a 2017 f20).
I've also ordered the following:
gps antenna:

nbt emulator:

Hoping these are the right and compatible parts.. And is there anyone that knows a good guide on the e-sys part? If anyone would be interested in helping me with the code part, I'll pay happily
Looking forward to the install!
Thanks!
