Summary: Sony has positioned the otherwise good NV-U84 GPS device in an odd spot, where it's not as good a value as the models immediately above and below it in the NAV-U lineup.
Pros: The NV-U84 GPS device has a huge 4.8-inch wide screen and is easily viewable in direct sunlight. Position Plus makes navigating areas with spotty satellite reception more precise. The Super Suction Cup allows dashboard mounting as easily as glass mounting.
Cons: For a device with no Bluetooth and no traffic data, the $349 price tag seems a bit high. The jumpy auto-complete system actually slows down destination entry.
