Unit works and has saved me from a few incidents over the years! I have a pile of different mounting options, including a remote power setup where you can tap into a low voltage circuit in the car and tidy away the cord. I had this mounted to my rear-view mirror and cord ran up and around windshield and to the fuse box, tucked behind the headliner and pillar trim pieces – for example. The piece of Velcro was to allow it to fit snug in the mount without getting scuffed up by the mount.
