The visibility isn't that bad after you get used to it. During my test drive I thought the visibility was quite bad after stepping out of the Avalanche. LCA and parking sensors work really well, but having the backup camera allows you to get even closer when backing out in a tight spot. I could honestly live without it. There are aftermarket kits that you could retrofit if you ever feel you need it.

 

Although it can be done without a backup camera, it is a lot easier with it. I ordered mine without it, regretted it, and ended up putting the NavTV unit for around $1500, well worth it.

 

No, IMO. I thought I would miss it after having in my last car and in the wifey's RX, but the if you did opt for the park assist, that works wonders. I've never relied solely on the camera anyway. Assume it's a nice to have, but definitely don't feel it's a must. Again, just my opinion.

 

It's a life saver for tight space parallel parking. You can literally get within inches to the other car. There is no way you can do that with parking sensors and visual.

We've had it in our Toyota minivan, our Cayenne, and will continue to get this option for all our future cars.
