The Garmin Streetpilot 2720: If you're looking for a premium vehicle GPS navigation system, one with text-to-speech and the ability to gather real-time traffic information, the StreetPilot 2720 is the answer.

In addition to the turn-by-turn voice-prompted navigation available in earlier StreetPilot models, the 2720's text-to-speech functionality allows the unit to audibly announce the names of upcoming streets and points of interest, letting you keep your eyes on the road while navigating through busy traffic and tricky roadways.
