Curious as to where the factory mounted microphone is positioned for the OEM installed bluetooth system?

I assume on the drivers side A pillar?

It's under the drivers side tweeter grill on the dash.

Thanks for that.

Don't know if that is too far or not but for additional example, the outlander has it at the top of the a-pillar which is closer to the driver.

Couple of other threads here on factory bluetooth, incl mic position and firmware updates

Have a look at
