Please help: 2014 M235i trying to add enhanced Bluetooth using E-Sys

2014 M235i base system; I believe iDrive 4th Generation: NBT
S663A bmw radio professional
Entry headunit and do show CMB_Media in the coding window
Trying to add enhanced Bluetooth

Background:
First tried using Bimmercode, but my Headunit is showing “coding data invalid “.

Now trying E-Sys.
Im using 6NS from 6NH in FA (although seems some info says possibly 6NK)

I get through all the steps, change Salapa to 6NS. Verify it was written. Then go to final steps as noted here:

4. Once all steps are complete: go back to expert mode, Coding =>
right click FA and select activate FA =>
Click read SVT
Right Click on HU_CHAMP2 (HU_NBT for NBT Pro Media or HU_EntryNav for newer business media) (the ECU itself not the underlying CAFD) =>
Select CODE
Wait for 'Abarbeitung beendet' which means finished completed.

Right-Click on CMB_Media (step not required for NBT pro media or newer business media) (again the ECU itself not the underlying CAFD) =>
Select CODE
Again wait for Arbarbeitung beendet

6. Click disconnect, Done!


When I click "SVT", I receive an error (pic attached). Have read some issues with this, so choose "Read ECU" instead and can see my modules. I do not have HU_CHAMP2 or HU_NBT but do have HU_ ENTRY (attached pic) and CMB_MEDIA. When I right click HU_ENTRY, "code" is greyed out. When I click CMB_MEDIA, I can choose code and do get the message "Arbarbeitung beendet"

I reconnect my phone, go to my IDrive screens and still no configurable Bluetooth choice.

Thanks for any assistance at all - been frustrating. I also previously removed all Esys related downloads and reloaded everything to no avail.
