I looked at the schematics, and the BT chip is directly connected to the audio chip.
The BT chip setup is done by bluez, and it appears pcm in/out is always on and no additional setup
required (other than pairing and setting up the headset).

If it is it is totally beyond me to see where and how this would be setup

I think bluez driver already does that. I made it work on my PC for instance.

That also seems to be set in the .state files which are GTA01 specific, I created some GTA02 ones
but no hint of audio thru BT. (I probably missed something like the Neo Mode setting, but wait..
they took that out and did not document what it was replaced with!)
I officially give up on this, as I simply cannot make any further progress, I have uploaded the
gta02 compatible state files to the wiki, and I hope someone with more patience than me can guess
the rest, because guessing is about all that is left.
I am totally frustrated by this, and the total lack of interest by anyone at OM to get this working.
I am very close to sending the FR back under false advertising laws, as no working BT headset makes
it useless as a GSM phone in the state I live in, and it is advertised as having BT headset
capability and I have spent a lot of time filling in for OM to try to get this to work.
If OM can give me at least a time frame when they can look into this I'd appreciate it, because I am
starting to think that BT headset will not work in GTA02, like it didn't work in GTA01, and OM is
avoiding having to admit that publicly.
All other conspiracy theories are welcome ;)
A VERY frustrated user!
