Mein Auto: 320i
Coder Wannabe

I've obtained a cable and e-sys software (3.24.3) and have successfully tested connecting to my 2014 320i (F30). The car came without navigation, with a combox in the trunk and with BMW Assist and was manufactured 2014-02-27.

I've been reading and reading, but still have questions before proceeding. I don't want to "brick" my new car.

As a first project, I want to add enhanced Bluetooth.
1) Do I change 6NH to 6NK or 6NS? (I read a post that said it depends on the head unit firmware and whether the car has BMW Assist, but I'm not sure how to determine the firmware date.)

2) What's the appropriate way to backup everything before I start, so I can recover if there's some sort of problem? And how would I recover?

3) I'm following the instructions in a help document named e-sys vo coding guide.pdf which is titled "How to change FA (VO) in F-Series car Version 8-24-2013." Changing the 6NH to the correct code for EBT seems pretty straightforward, but once that's completed, I apparently need to "VO Code" CMB_MEDIA and HU_CIC/HU_ENTRY or HU_NBT, and I'm not certain what that means.
I think it means that I need to follow the steps on the very last page of the vo coding guide.pdf (titled "What Next?") which describes right-clicking on ECU and selecting "CODE." Is CMB_MEDIA an example of an ECU which needs this right-click/CODE process? Is the changed data then immediately written back to the car by the CODE command?

4) Is there any way to "practice" any of this offline (perhaps using backup files)?

5) It appears that there's a different process if I want to change most other features (e.g. add digital speedometer to the BC cycle). Is this "FDL Coding" (as opposed to "VO Coding")? I've found documentation for FDL Coding including a YouTube video by TokenMaster. Are there different backup techniques necessary for that?

Thanks for bearing with these newbie questions. I'm sure this will all be less daunting once I've coded a time or two and understand the abbreviations and buzzwords better.
