Query: It got me out of a jam.

I purchased the RoadMate 760 portable after a very favorable experience with the Hertz Never Lost system in Oregon. I live in California and have used it to find businesses while on a camping vacation and in nearby cities. On our anniversary, we were able to use it to pull up phone numbers for a movie theater and a restaurant where we checked showtimes and made a reservation. So far, my best experience happened after a concert in the Sierra Nevadas. The crowd was very large and traffic was stalled. We hadn't moved for about 45 minutes. I picked shortest route, surprised that it could find where I was at about 5,000 feet in elevation. It gave me an alternate route. It was a washboard dirt road, but I got home well before the rest of the crowd. It's been very accurate and my technophobe wife feels comfortable using it. Being able to move it from car to car with two college-age children is also a big plus. Each plans to use it on their next "Road Trip."
