Yes there is. On the right hand side there's an indented circle which is the blanker for putting a 12v socket in. Behind there is the power supply with a connector on it waiting to be connected up.
So you can fit a 12v socket there by drilling a hole in that circle and adding a socket, or you can fish for the 12v supply to hook up something custom by opening up the rectangular panel to the left of the circle blanker.
I can take some pictures if you like but I'm away from the car for a week.
