I put the peak one on mine last year, had to go with the smaller monitor one, because there was no were to mount the 7 inch without it being in the way. never really had any problems with it, works good, I dont have or use blue tooth so cant speak on that part. only annoyance with it, is that it does sometimes pick up stray signals from other wireless camera's, business or home use ones. and the blue light on it get anoying at night, I painted mine over so i dont see it blinking at times. hookup is simple enough, used the factory mount for on the lisence plate. I do want to re wire it so that I can either turn it on whenver I want, or push the switch and have it come on only when in reverse though.
