Not sure what you mean by a pillar but will look for the mic and see how that goes.
A-Pillar is the left and right frame of the windscreen. There is a mic shape hole on the A-Pillar interior plastic trim. If you (driver) talk to top right corner of the windscreen, then it should pick up the voice. If the passenger want to do anything, then the passenger should talk to top left corner of the windscreen. There are two mic in the car so that the car can work out who is talking then executes certain instruction to that side only (e.g open window or adjust aircon temp).
