thanks, i assume by "sees through the headlights" you mean you are powering the camera system through the headlights? there are some cheapie systems on amazon and ebay for like $50 that include wireless transmitter and camera and i might just try one of those and use an old phone as a monitor. i also like the idea of always on or being able to turn it on so i can see what's going on back there when not in reverse.

Thanks, but too kind. The truth is that, after 2-1/2 years, I completely forgot how my system worked and substituted a hallucinogenic alternative about sending the info thru my 12 volt system. You are, of course, correct. My cam uses running light power, and sends it's output to my monitor over the ether. The monitor plugs into the 12v port formerly know as the cig lighter receptacle.
The only thing I got right was the system reliability. It has always worked, and has provided us with peace if mind w.r.t. bikes riding correctly in the rack. I can also point it back when the bikes aren't with us.
I'm sure the systems have gotten cheaper, but I would do a little research. If only to avoid excess mounting holes from jetting your first choice, and having to drill more for your second choice. Ours is RVS. China made. 5" screen. I would not use a phone for a display. Too small, and doing it right is not that many $...
