Sony has released a second model in its Nav-u series of satnavs, this one called the NV-U71T, which is slimmer and easier to use than the previous model.

The NV-U71T comes with an RDS TMC traffic receiver built into the cradle and a subscription for the first 90 days of use; continued service then costs $4.95 a month.

Sony has also simplified the user interface, and has added a Gesture Command function that lets you go straight to the most frequently used commands, like “take me home” by drawing an inverted V on to the screen with your finger.

Specifications include a 3.5-inch screen with anti-glare coating, and a weight of only 9.9oz.

The device, which is currently only available in North America, comes with preloaded maps of the US, Canada, Alaska, Hawaii, and Puerto Rico on its 2GB of memory, and stores over 7 million points of interest, which is four times as many as the previous model.

The NV-U71T can be pre-ordered in either metallic blue or silver, and costs $500. A second vehicle kit with bracket and charger costs $100, while an external GPS antenna costs $100. The travel case will retail for around $30.
