I traded in a 2007 CR-V last year with 150K miles for a 2012 CR-V with 90K miles. The reason I went with a 2012 was because I wanted the rear-view camera, and the 2012 model was the first CR-V to have it.
We put high end Pioneer navigation car radios in our CRVs, in part because they come with rear view/side view, and front view cameras. I don’t use it, but there is a feature which allows the rear view camera to remain on while driving. I find it too distracting, but it does give an excellent view of your blind spots.
