I *think* I unlocked enhanced audio in my BMW X3 2014, but I am unable to to enable it. I followed "E-Sys - How to change FA in F-series car" and "https://www.youtube.com/watch?time_continue=11&v=xbO4yWIFXoA".

This is what I did:
1 - installed E-Sys 3.27.1 - Preferred version (All functions work)
2 - installed Launcher Premium 2.8.x (w/ Built in Token Generator) - Alternative free solution
3 - Latest PSdZData_Lite (~2.5 GB) WORKS FOR ALL FDL CODING & VO CODING
-- I extracted the PSdZadta_lite to C:\Data\psdzdata\

4 - Now, i started to tap in the dark. In the string box, I had the term '6nh', which sounded familiar. The term "6nh" was appearing in several forums, googling "6nh" showed up in google as well and the above listed youtube video said '6nh' as well. I switched this to '6ns'.
5 - saved it and applied it
6 - wrote it back to the car

7 - un-paired my phone
8 - turned off the car
9 - started the car
10 - paired my phone again, but it only says calls only
11 - bluetooth shows up, but I am not able to enable it?

This forum post: https://www.bimmerfest.com/forums/showpost.php?p=8020396&postcount=7 says "* Note: 6NS is used for NBT Head Unit. For cars with 6NH and ENTRY or CHAMP2 Head Units, use 6NK, or 6NL if car is equipped with BMW Assist."

I got 6NH, not sure what ENTRY is, but it says HU_CHAMP2 (https://imgur.com/a/h5HMGnw) and I do not know, if I have BMW Assist. That said, I guess '6ns' is wrong and should be either '6NK' or '6NL'.

Which one is it?_a_

What about this step:

Repeat Step 2 above for and standalone Combox (CMB_MEDIA) if present.

* Note: 6NS is used for NBT Head Unit. For cars with 6NH and ENTRY or CHAMP2 Head Units, use 6NK, or 6NL if car is equipped with BMW Assist.
For HU_NBT and HU_NBT2 (which you do not have), combox is part of ECU. For cars with CAFD_000000F9 (eg, HU_CHAMP or HU_CIC), it is separate. Do you find CMB_MEDIA or CMB_ECALL?

BMW Assist is if you have SOS option.

Well, I know I have the "RED" button, but I do not know if it is active or not.

CMB_MEDIA and CMB_ECALL, where is that located?

Hi,
just wondering if you got this working as i think i have the same problem. I had ebt coded yet i still cant stream audio as the phone recognises the car as a headset rather than a speaker. This is no doubt because i cant enable Bluetooth Audio in idrive. I can find the setting screen but the box is not tickable :mad:

Did changing 6NK to 6NL work for you?
