When I park on a city street I can return to the message "x sentry mode events" where x can be a large number (max for me is 32)! They are usually just of people walking past. I do a quick circuit of the car to see that nothing is awry and so the 32 videos can be deleted. But how? It's a pain to remove the drive and delete them on my computer and doing it by hand in the car is time-consuming. What do you do?
