I just took the Nuvi 350 on a 5-hour road trip.. And I'm even more impressed! Going to New Jersey I'd been advised to take the Tappan Zee Bridge.. So I plugged in the New Jersey address and inserted I-287 in Nyack, NY as a waypoint.. It led me there on almost the exact route that I'd planned out using an atlas. If you diverge from the path it wants you to take, it recalculates within seconds.. It has a nice auto-zoom feature, so you can have it zoomed out a little farther to see what's coming up ahead...but it will zoom back in temporarily as you make a turn. It also has a great trip computer.. It tells you your GPS-measured current speed, distance traveled, distance to destination, overall average speed, average moving speed, max speed, total time, time moving, and time stopped.
My results:
Total Mileage-359.01
Overall avg- 56.4 mph
Moving avg- 66.2 mph
Max speed- 102 mph
Total time: 5:42
Moving time- 5:25

And the 330 averaged 27.2 mpg! I only used 3/4 of a tank.
