Any of the vids of mine that aren't handheld have been shot on that mount. There's just enough room for the camera to sit straight up and not hit the glass while driving over rough terrain. Take a look at the dimensions of my camera (Olympus 770SW) to determine if your camera will fit. You can always mount it upside down and flip the pics/video in another app.

 

We have a Sony DSCW120 and it is about he same size as your camera.
I found a how to to make a camera mount that mounts to your headrest posts.
I am not to worried about it right now, i need a new laptop first, it's all I can do to surf the net, I have a vid from our Christmas trip but I cant post it on youtube, and it is only 45 sec long.
