I installed the factory back-up camera/monitor in my 07, SR5 Tundra today. It has the tow package so everything was plug and play. All the wiring harnesses were in place. It took about two hours to do. I could probably do it in an hour now that I have installed one. The monitor replaces the sunglasses holder at the front of the overhead console. The camera fits into a new tailgate latch that has to be installed. The camera does a nice job of providing a clear view of what's behind you.
