well the one I received today was the "for sale" navusII. The molding of the plastic is different. On the left side of your picture it shows a circular set of holes. Mine has fins there. It wasn't three times the cost though. They can be had for 769.00. But I got mine for 500.00 . The way it installs is part of why it costs so much more. It is a seemless install where no wires are shown and everything plugs into the factory wire harness under the hood. I don't know if that is worth the extra cost to everyone, but it is to me.
