a good investment if you already have a compatable next base dash cam, I have the 522w and it works well ,I fitted my self it runs from the front of the car plugs in the side of your dash cam ,wasn't too hard to run the wire from front to rear ,just make sure you leave enough length at the rear to allow for freedom of movement,check out fitting videos on you tube ,once connected you can switch between front and rear view on the dash cam ,it records both at the same time ,but I do prefer to watch the rear on mine when im driving .
