Your best best is to stay in the Acura family! Both the MDX and RDX offer all of these features! BMW is just starting nav-traffic, but non of their SUVs have a back up camera.
The Upcoming Ford Flex has all of the features you've listed too!
But If you need it SOON, the 04-06MDX has everything but Nav-traffic and the 07+MDX has everything you've listed.
