Taking it out and having a look would have taken a lot less time than typing the question.
However, if it is the one that came with the cam, it is likely a 16GB card.
Why the reluctance to take it out anyway?
For goodness sake. Satisfy yourself by the simple procedure of 'take it out and look at it then put it back in'.
It's unlikely that the manual will tell you. And how will you know whether it's right or not even if it does.
I suppose that you do know how easily the SD will pop out/in? The only 'danger' is losing it on the car floor if you let it pop out quickly.
I'll ask again. Why do you have an aversion to take it out anyway?
