The StreetPilot 2720 is a premium GPS automotive navigator that offers text-to-speech and traffic interface capabilities. 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 name of upcoming streets and points of interest (POIs), letting drivers keep their eyes on the road while navigating through busy traffic and tricky roadways.
