In view of jokiin's comment I had another look. And he's quite right, with the cable cover off, the cam can be removed from the base.
If, like me you need to remove the cam to remove the card (my cam is on the right of the mirror support), and you do this quite often (in my case to transfer the recordings to HDD), then having to also remove the cable cover becomes all very fiddly and awkward. An alternative method would be to leave the cam in-situ and connect a laptop to it to transfer recordings. Then nothing need be removed.
