I'll add my $.02.. I installed this years ago and it works great. We have no rear windows, so I wanted what the OP wanted.. an always 'on' rear view when driving. I have it wired so that it turns on with the engine ignition, then off when you shut the motor off. You don't touch a thing. Not the cheapest out there, but I've no issues with it. I epoxied the monitor to the rear mirror mount on the windshield and it looks stock. As a bonus, you can run two other video feeds to it as well (you switch the channels with buttons on the monitor). Good luck!
