I personally used velcro, which i purchased at Home Depot pretty cheap. Otherwise, there's the Muvi Extreme Action Sports Pack that has a lot of different mounts and attachments. Those in combination with some velcro should get it attached to your car with a good viewing angle. For what it's worth, i've upgraded to the Muvi Pro VCC-005 as my dash cam, using one of the included mounts + velcro to get it on my dash. With the screen and actual menus, it's a little easier to deal with (though it costs more).
I haven't seen or heard of any, i use mine on the passengers headrest , i think this location gives you the largest recording area. If you are able to that is . i use a headband from a flashlights you wear on your head to free both hands to wrap around the headrest. it works well for me. the only catch is empty pass seat . I'm thinking of making one with a spare mini usb and some glue . a simple solution just haven't got around to it.
I ve only seen these on amazon or e bay.if you can find a standard camera mount and you have the weather proof vase you can use that because the weather proof case for the micro view will fit a standard mount.
