The nuvi 465T is Garmin's first navigator designed for the over-the-road trucking industry and will navigate routes based on your truck's type, load and physical restrictions. When navigating, the 465T can display upcoming road conditions and warnings to make drivers aware of possible hazards along the route, such as sharp curves, steep grades and road narrows. The n vi 465T is also the first GPS unit to link locations in the National Truck and Trailers Services (NTTS) directory to truck relevant points of interest.
