A blind spot monitoring system is a great investment in improving the safety of you and those around you while driving in heavy traffic, changing lanes, or merging into traffic. While different blind zone systems work in different ways, they all have the same goal: to help you find out if there's an unseen vehicle in your blind spots.
This system uses two cameras, mounted under your outside rear view mirrors, to watch your vehicle’s blind spot areas. Display mirror connects to turn signal wires in vehicle, when turn signal is on, that respective side of the mirror will show that side camera. With the mirror you can also add a rear camera (9002-7601 or any camera with RCA end), that will show full screen, with or without park lines on mirror display.
