Garmin Nuvi 880
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.

Asus R700t
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.

Dash Express
The two-way connectivity of the Dash Express portable navigation system offers powerful search and traffic capabilities to drivers and increases the value of GPS to the next level, but the system needs some refinements before we're willing to invest in it.
