trying a different card reader is always a good idea, extension cables can be an issue also
memory cards aren't hot swappable, camera should be powered off when removing or inserting the card, just stopping recording isn't the same
have you checked, it review says otherwise
I bought this camera because recently, someone made a dent in my car while it was parked. This camera has an internal battery and a shock sensor, so it can wake itself up from standby.
the dashlight doesn't need to be in the field of view to still be a problem, in total darkness the flash of an LED will easily keep tripping the motion detect, try covering it and see if you get the same result or not
