im starting to think (based on my usage and what others have said) that these lockups arent occurring off of freshly formatted cards + hard reset of the hardware. is it possible virb edit and/or removing the old files is giving the camera fits?
i plan to hard reset the device each time i plan to go use it and to format the card as well. if others want to try this and report back maybe we can isolate the issue as garmin continues with the "this is not a known issue"
