I bought the suction mount off Amazon which did work with my Cat1 camera. It is too small for this. I guess the best bet is to buy the Garmin one and then return it if it doesn't fit. I wonder if they ask which version you have on checkout, but seems unlikely.
Here is a picture of one of the accessories that came in the box with the Cat2, held against the Cat1 camera. It is too large. They are different sizes. Unless I'm a moron...which...you know...I'm accused of sometimes.
