The Bottom Line: The Navigon 8100T offers an impressive feature list, including panoramic 3D map views, but the GPS doesn't deliver where it counts most: performance.

The Bottom Line: With the new interface and additional navigation features, the Alpine PND-K3 is an improvement over the company's previous in-car GPS, but the expensive price tag is a turn-off, especially when you can get more for less.

The Bottom Line: As we've come to expect from the Nuvi line, the Garmin Nuvi 880 offers an impressive feature list and solid performance, but it's the accurate speech recognition that really pushes the Nuvi 880 over the edge and makes it one of the best GPS we've tested to date.

The Bottom Line: For the company's first stab at the GPS market, the Asus R700t is an impressive debut, offering some great navigation features. However, we'd like to see the addition of text-to-speech functionality and smoother performance before completely committing to it.
