I am in the process of installing it on the edge. I still have tie in the power for the mirror into the edge existing mirror power feed instead of use a 12 volt plug.
I have the Sel version of the edge and it does not have a backup camera. (You have to get the Limited Model to get the back up camera) After market Back up cameras cost from $500 to $600 so I decided to give it a try even though I do not need the Bluetooth (total cost$180+tax).
With respect to the install it was a bit tough to tie into the backup light power source when the light is not located in the door or hatch but in the tail light assembly. Once installed it works well. The only thing I do not like is the attachement of the camera to the rear Licence plate with just an adhesive pad.(no bolts or screws)
"How long will it last?" is the question that I cannot answer. We will see. We have small children and we are in and out of daycare all the time so it is needed. Having it may save a kids life or at least save, a toy or a Tricycle
