My issue now is that I have an adapter with latest Broadcom stack. I'm using that and PhoneControl software (inside CentrafuseXLE). Windows can see the phone, and see the headset profile. Everything mentioned is supported through both my adapter and software. But still, neither PhoneControl (in CF) or FreeFone (in RR) can see or interface with my phone, although Windows sees it fine.
It shouldn't be this difficult. It's as if the program (PhoneControl/FreeFone) isn't talking to Windows. Windows sees the available services, the phone programs say that there are no supported services.
Since I know better, and know that this does indeed pair with OEM car systems, this should theoretically work. I don't see a single thing holding me back, besides this invisible wall of confusion that I can't figure out.
