I bought this 2 months ago It has the special GPS system which can tell you if theres a speed and red light camera ahead which includes the speed limit. Built in speedometer other normal additions. The one thing which made me hate this Dash cam is the save button function, it will only permanently save the video once you press the button. Which means it wont save the previous 1 minute, 30 seconds or even 5 seconds, it will only save after you press it. for example; when an accident happens it you can only start saving after. Which defeats the purpose of the save button. I think they expect you to predict the accident before it even happens.
