Sony's Nav-U line of PNDs hasn't made big waves in the States yet, but the company's keeping at it, releasing four new touchscreen navs today. The new $400 NV-U94T (pictured) takes over from the NV-U83T
at the high end, featuring a 4.8-inch touch screen in a 30 percent thinner case, gesture commands, POSITION plus accelerometer and barometer (wild)-based dead reckoning in case of signal loss, Quick Links POI icons, and an RDS-TMC traffic receiver built into the cradle, as well as basic PMP functions, Bluetooth with A2DP output and Memory Stick Duo expansion; the $300 NV-U74T is basically the same package minus the PMP features and with a 4.3-inch screen and the $350 NV-U84 keeps the 4.8-inch panel but doesn't have Bluetooth, dead reckonings, or traffic. There's also a totally new 3.5-inch unit, the $250 NV-U44, which is pretty basic but seems like a fine deal: text-to-speech nav, maps of the US and Canada, and split-screen 3D views with lane guidance. All four should be out in September.
