top marks, that's exactly what it's for!I've been wondering this myself. My only thought is that it is just for airflow so your phone doesn't overheat if you mount it in there.
That's where the knock-out gas is pumped from, at the passenger, if you specified the James Bond option package. In this option, the cabin temperature sensor underneath the AC buttons is used to detect if the passenger is a megalomaniac stroking a white cat, as otherwise the gas isn't released. The gas is used to avoid the expense of fitting a new panoramic sunroof, as that gets blown off if you use the ejector seat.
I mean, come on people, read the ****ing manual - this is all basic stuff.
