We like the idea of a large touchscreen but the Uniden GNS 8600 is a little too big to be practical, despite its excellent features. The lack of an internal battery, slow interface and high price tag all count against what could have been an excellent product.

The S102 comes at a good price, but although the navigational experience was solid, it just doesn't do enough to command a glowing rapport. There are plenty of better options available on the market.

Despite being an entry level unit and commanding a very reasonable price tag, the Navigator 3000 falls short in a few areas.

The FD-250 has most of the basics and a few extra features that will serve you well, but the lack of responsiveness of the touch screen is an issue.

Although the GPS 60 looks like it means business, it doesn’t live up to expectations. A USB connection and Garmin’s MapSource software are small consolation for the lack of mapping and slow signal acquisition. There are better — and cheaper — handheld GPS options.
