Need help with aftermarket android headunit (2018 CX-9)

[slashers]

Hi all, I just recently received a android stereo for a 2018 CX-9 apparently it comes with bose support and it comes with a curious feature, it can choose which system I want to use, it can be OEM or android. The interesting piece is that after connect all the harnesses, if I use the OEM, everything works flawlessly but if I choose android, everything works but no audio. I'm still trying to figure it out, a configuration? Extra wire? I just read a couple of post (not for a cx-9) and some people say, it is because Bose needs to power up with 12v, others said I need to purchase a PAC but I'm more on the it is a configuration, any idea? Suggestion? Pretty much I don't want to purchase that I don't need and can be solve with a silly thing.
