I installed a backup camera on my '05 duramax a few years ago, also backup sensors. The backup camera is fair, not great. I keep the backup sensors turned off mostly because the noise is so high and piercing, even with my bad hearing, that we can't stand it. It has a high and low setting, but the low setting would wake the neighbors up. Also, the taped on dash monitor is pretty dorky.
So, in summary, I haven't been all that happy with aftermarket cameras and sensors. I don't know why they make the sensors so loud and irritating. She loves her '03 Sequoia and won't trade it in. Can't blame her though, feel the same way about my Duramax.
