V1 - but like any device you have to know how to use it...by itself it will not save you...had it for 8 years and dont go anywhere without it...false alarms? sometimes but I take any alarm serious that way I am always on the safe side...always slow down when approaching steep up and downs, and blind corners, otherwise just floor it...once you use it over time it becomes second nature and you will see the cops before they see you...
