Panavise works if the camera has a tripod mount. I wonder if you could mount the suction cup on the panoramic roof? I think I tried that with a cell phone/handheld GPS holder and the dash camera without much luck, but it may have been the holder itself was inadequate. A camera mount for something other than a point-and-shoot would likely have a stronger suction cup.

This camera is OK, but as one review said, it is inconsistent in when it records. I found times when it appeared to be running but there was no file when I checked the SD card. I put in a new card and got similar results, so it's in the toybox where all of the other retired toys reside.
