Default [F22] MOST bus audio enable help

I know most of you are more familiar with the E series but I need some help with my F22.

I am trying to install a moBridge DA3 which basically uses the MOST bus to output 8 RCA channels for external aftermarket amps. However, the F22 never got the upgraded amp that uses the MOST bus so the head unit outputs analog audio to the amp from the factory. To use the DA3 i will need to code my head unit ecu (and any others) to output audio over the MOST bus.

So far I FDL coded AMPLIFIER_VARIANT to "most" (from external) which sort of worked. Music from all types of sources (radio, bluetooth, ipod) stopped playing from the factory speakers/amp and the PDC beeps and system gongs started playing out of the DA3. For some reason the music audio was not playing out of the DA3 though.

Anyone know what I need to code to get the full audio output through the MOST bus?

For the 1 series it looks like all it takes is to code:

AUDIO_SYSTEM: hifi_system_harmankardon = 06 (this is my default)
EXTERNER_MOST: aktiv = 01 (also default for f22)

VO is set to 677

I got an error when I tried to VO 677 to my car. Something about not having the correct hardware so I stopped. Maybe it works if you continue?

Thanks for anyone's help in advance!

I figured it out for future reference. All that needs to be changed is the following:

AUDIO_SYSTEM: tophifi = 02

Not sure if AUDIO_SYSTEM even needs to be changed but that's what it was when it all worked.

Im assuming EXTERNER_MOST: aktiv = 01 needs to be true as well but that may be default for most people.

Hope this helps someone in the future from pouring many hours into research all over the place to figure this out! It seems so simple now...
