Garmin StreetPilot 2730 - 3.7 in. Car GPS Receiver

I recently upgraded from the Garmin 2620 to the 2730 and LOVE both devices. I recently went on a college tour with my 16yo daughter to scope out prospective colleges for her. We visited 8 colleges in five days, and traversed 8 states, and NEVER BOUGHT A MAP. We started in Burlington Vermont with a rent a car, and flew out of Norfolk Virginia. One of the colleges was in a remote part of Vermont, it was snowing, thick fog and nighttime. No problem. The GPS found what was nothing more than a long driveway and took us 2 miles in to a farm/college setting that seemed out of a Thoreau winter wonderland. Then it guided us uneventfully to an urban college on the outskirts of New York City, only to leave us with the horrific prospects of driving through The City during rush hour. Not a problem. 5:45 pm through Queens, over and among the tangled freeway ramps, onto the Jersey Turnpike and by 6:30 we were well on our way to Annapolis, Md. The GPS seemed to know where the congestion would be, and routed us around it. The only time we had trouble was when the college didn't give out it's street address (they said it was meaningless, which proved incorrect) and we had to rely on verbal instructions from a receptionist. We were within a mile of the campus, called, and the very first instruction "turn right at the light" was wrong. We finally did find it by googling their address on a cell phone and then using the GPS to guide is in. OH, and did I mention that we never bought a map...AND that we've never been to this part of the US before? Anyway, our thanks to all who make this fabulous technology available and useful. (PS: I was a cartographer for several years)
