Great GPS for traveling with a rental car

This very reasonably-priced GPS has the color screen and routing features of the big guys, but small enough to slip into your shirt or coat pocket and run off the built-in lithium-ion batteries. It's 100+MB memory will hold detailed maps and points of interest (e.g., restaurants, attractions) for large chunks of the U.S. (e.g., almost the whole state of Texas) where I frequently drive. I then add in a few maps when I plan to travel to a new city using the USB connector. I even sent it with my wife and daughter (along with a short instruction sheet) on a recent tourist visit to Colorado Springs. They successfully used it to navigate to about a dozen attractions and never got lost with the rental car!

Note that to get the voice prompts while driving a calculated route you must use the 12V car charger. The handheld unit itself does not have a speaker.

The Quest also supports a remote antenna, which let me then mount the GPS in a less obvious location (i.e., less likely to attract thieves) and less susceptible to solar heat damage in hot Texas summers.

I used the Quest on a recent cross-country airline flight (sitting in a window seat; got a few strange looks from the flight attendants, but they didn't throw me out or anything :-). Putting it into "off-road" mode, the GPS calculated our route to the destination airport, and accurately predicted our arrival time within five minutes! Even with just the U.S. base map, it was fun to be able to identify locations 7 miles below. When I got home, I downloaded the trip log and was able to make a map showing the course and altitude.

The only negative thing I've found is that it would help if the screen were just a bit larger, for the sake of my over-50 eyes.
