The rear-view camera in our X5 is just awful, as well. I'll be curious to see if they improve it before adding it to the new 7. As is, it's often useless.
I am interested in the X6, but the rear visibility issue really concerns me. For those of you who have had your X6 a while now, is it something that you adjust to or does the visibility issue remain?
