On my '02 Civic SI (and in every picture I have seen of the same vehicle) there is a round blank on the right side of the center stack, just to the right of the gearshift. What is supposed to be there? Some option nobody has? Or ?????

Perhaps a cigarette lighter for those that smoke? But then what about the 12v socket at the bottom of the stack? Of course, I think you cannot put a cigarette lighter in the 12v socket down there.

Anybody have any ideas? Or has anybody installed something useful in that hole?
