I think "excellent resolution" is subjective.

Some people don't even care about seeing things clearly (ie: my father-in-law still thinks his old projection TV is just as good as my HD. He even claims. Mine screen is bigger too!). But for those who do, Once you see and get used to things in the higher resolutions, it's pretty disturbing seeing things that doubt match up. That sounds like the gripe of most that complain about the backup camera anyways. I'm sure they've used ones in a Japanese import or other brand which is superior and are thus complaining. Some (if not most) of us drive BMW's cuz we want to be better than the rest. Heck, we sure pay a whole lot more for it. And having a subpar backup camera just sucks.

But rather being so unhappy all the time, we really should try to be happy. At least it works and there is one equipped. Plus it does have guidelines.
