Thanks, yes that's correct, I had assumed that the car must have come with a plain piece for the floor and then owners can afterwards replace it with the phone cradle piece.
Anyway, the dealer parts department has actually faxed me a diagram showing that the OEM replacement for the cradle is a cup holder!!??
As you can tell I’ve bought the car 2nd hand and assumed that the phone cradle piece must have been an option, but did it actually come as standard??
Good idea about the mat, I’m not averse to doing something like that, just wanted to do it properly if possible with an OEM part.
