I sent another email to
bimmergeeks (Protools) asking:

I am assuming that mute functionality is disabled,
simply because the pin is labelled ‘radio mute – INPUT (E)’ by BMW.

Answer:

Would really depend on the daten file in the headunit, but brief look there are the coding options:
MUTE_PIN_BEHAVIOUR
MUTE_PIN_SOURCE
|
I checked with NCS DUMMY and found the following:
MODULE : CIC
SECTION : AUDIO_TUNER_TRAFFIC - Audio tuner traffic messages
SUBSECTION :
MUTE_PIN_BEHAVIOUR
OPTIONS : no_function/permanent/trigger
SUBSECTION :
MUTE_PIN_SOURCE
OPTIONS : no_source/mono_aux_mixed/mono_aux_exclusive/stereo_aux_exclusive/entertainment_mute/security_exclusive
SECTION : TELEFON_TELEMATIK_ONLINE
SUBSECTION : MUTE_BUTTON
OPTIONS : aktiv/nicht_aktiv
VERSUS
MODULE : CCC_APP_{C09/C0A/C0B/C0C}:
SECTION : CKM_9901 - Car/key memory for programmable buttons
SUBSECTION : K9901_MUTE_EIN - Programmable button for audio muting
OPTIONS : par_frei - parameter available
: par_gesperrt - parameter locked
QUESTIONS:
1. Is K9901_MUTE_EIN (CCC) used to enable/disable the existing mute button on the volume knob?
2. Is K9901_MUTE_EIN (CCC) the equivalent of TELEFON_TELEMATIK_ONLINE (CIC)?
3. Shall I conclude that the MUTE_PIN cannot be programmed with CCC?
4. Shall I conclude that the MUTE_PIN can be programmed with CIC?
