The nvi 350 is first and foremost a personal GPS device. Wherever you go — in your car or on foot– the device offers extremely accurate position data, thanks to a high-sensitivity integrated GPS receiver by SiRF and WAAS-enabled, 12-satellite reception. Combined with detailed maps of the U.S., Canada and Puerto Rico the nvi 350 provides automatic routing, turn-by-turn voice directions, and touchscreen control– making it easy to find your way anywhere. Plus, the unique “text-to-speech” feature calls out turns by street name, and you can choose from either 2D or 3D mapping perspectives when you’re viewing your route on the display. Additionally, the nvi 350 is compatible with Garmin’s GTM 10 FM TMC traffic receiver, which allows users to avoid traffic tie-ups by simply pushing a button that will calculate a new route.
