I have a question about these backup camera systems. So when you backup, you're supposed to look forwards to focus on a little tv screen that's looking backwards? What happens to traffic approaching from the sides? When backing out of my driveway, or in parking lots, the place I'm looking most is out the rear side windows, for approaching traffic. Do these backup cameras offer a 180+degree field of view?Gills said:I did a 24-hour test drive of a 2007 Yukon Denali last week; its backup camera was soooo much better than the three-light backup sensor. Does take some getting used to though.
