Newbie question - Focus TDCI LX 06 plate MK2 Anyone know what the small vent/sensor thing is which is in the middle of the row of buttons, to the left of the heated rear windscreen button in the centre console? it looks like it could be for a microphone, vent, temp sensor or something. Can't see anything in the manual about it or on the net. I was thinking about putting my handsfree mic behind it when i fit it. anyone know what this thing is or have any suggestions where the best place for the mic would be? alpine suggest putting it low down in the centre console facing up towards the windscreen so i thought this might be a good place. thanks
