The Sony NV-U73T is a touchscreen GPS navigator that comes preloaded with maps of the entire United States, Canada, and Puerto Rico, and uses street name accurate speech commands via built-in speaker. Dual View map view can display important information on one half of the screen while displaying a 3-D map on the other half. Real Time Traffic Information radio reception lets you use your car radio reception to stay informed about current traffic updates. This model does not have the bluetooth capabilities present in the more expensive model in the NV line, the Sony NV-U83T.
