The StreetPilot 7200's huge 7-inch touch-screen display means you'll always see where you're going - from anywhere in the vehicle. Designed for larger vehicles such as RVs, semi-trucks, and buses, Garmin's 7000-series are premium automotive units that come preloaded with City Navigator NT detailed maps and display navigation, entertainment, traffic and weather on a grand sunlight-readable display. With the purchase of an optional sensor, the StreetPilot 7200 notifies you of accidents, road construction, and weather-related traffic delays before they are encountered, and then offers an alternate route. This optional traffic management capability makes driving with GPS essential, even if you know where you're going.
