sorry i meant the dimensions of the camera not the mount. what's the horizontal distance on it? trying to see if it fits behind my mirrori don't know the dimensions of the mount, but it looks like it's a little larger than the cf100 mount, maybe by a few mm in each direction.
i wouldn't be surprised if you can use a 128 in it. i currently have an old transcend 32gb class 10 card in it that was used in one of my smartphones for a year or so. i may later put one of my samsung evo 64gb class10 cards in it, once i get the action camera footage off it.
