Hello everyone- glad to join this forum to gain some experience on these Minidsp products!

I have a question about the future expansion plans on the Harmony DSP in regards to the A2B input.  Is the plan to have this integrate with Auto OEM A2B interfaces or more of a generic A2B for future Minidsp products?  I ask because almost every Ford premium audio system uses A2B already and I can't imagine them changing anytime soon.  There is an existing solution to interface with the Ford A2B signal- the Zen Audio A2B box- at a cost of $600.  I know the Harmony won't have direct control of the various volume control, fader, bass, treble adjustments, etc- but would it be able to decode all of the audio that's on the Ford A2B bus?  Think normal audio (radio, CarPlay, etc), along with any Nav prompts, phone calls, safety sensors, etc.

I  am very familiar with intercepting Can bus signals to see what codes are sent to change volume, etc.  I am sure I could write something that could interface with the MS-Can bus on the Fords to interface directly with the Harmony through its control interface.  This would make the Harmony an instant success over having to purchase the Zen Audio box since it doesn't have any DSP capabilities (it does have a slight time alignment feature for the driver) and no amplifier built in that could be used to run some of the many surround speakers the premium Ford trucks and cars have.

Any insight on future plans would be appreciated as I am deciding which direction I would like to go with my '21 F150.  Thanks!
