Just purchased and received this dash cam from Foxoffer. Installed and went for a test drive. The firmware is B40.20140523.001.
The file split is at default every 3 min interval. The "small pause", "jump" and "overlap" is noticeable and annoying. Just addressing my concern here that anything can happen during that millisecond frame and I hope if enough end users were to voice out, hopefully there could be an updated firmware release which can resolve this.
I will increase the split file to 5min interval to reduce the "overlap" frequency. Apart from this, I am still happy with the camera but with reservation. Fix this "bug" and I will not hesitate recommending to others!
