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: 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.
