Fugitive_Bill, you are right, maybe my explanation wasn't clear. I've edited my original posting to try and make it more clear.
Given a 32GB card, this is what the firmware does:
It records a 4GB, or 70 min. file (not quite sure which), then it starts overwriting the SAME FILE!! So, after many hours my 32GB will only have 1 tiny 4GB file. The remaining 28GB of empty space is still empty!!!! The firmware will never, ever start a new file. It just keeps on overwriting the same 70 min. file.
So, if I record 71 minutes (assuming the clips are 70 mins. long), I will have ONE MINUTE of video!!! - on a 32GB card!!!!!!!!!
This is certainly not common functionality for car dvr - at least I hope it isn't!
