I've been nothing but pleased with the Nav system. It's never let me down, and got me out of a couple of jams ( once in a Sierra snow storm at night! ).

I've had mine loaded with the full 1000 pounds of cargo, and crossed the Rockies with it loaded from L.A. to Denver ( Sea-level to 10,000 feet to 5,000 feet ) and got 34 MPG at 65 miles per hour.

I'm amazed more every day. Got a new job with a 9 mile commute ( vs. my old 1.5 mile commute ) and my cummulative FE is going up and up.

I'm in the mid-40's for MPG when driving in the mid-40's to 55 miles per hour day after day.

Cool!
