Looking for GPS device for your car? Sony has unveiled two new nav-u GPS devices for your car, the Sony NV-U73T and Sony UV-U83T. The NV-U73T model comes with a 4.3-inch with 16:9 aspect ratio display, and the NV-U83T model comes a 4.8-inch with 16:9 aspect ratio display and ultra-thin footprint. Both features text-to-speech functionality, the dual view, super suction cup mounting system and gesture command. The text-to-speech technology enables the voice prompts to actually say the name of the street or highway. With anti-glare coating, it is easy to see the screen in any lighting condition. With its high resolution, the device maintains a clear image even when the screen is split into two images. This unique dual view feature helps drivers navigate visually so they don’t have to rely solely on street signs. Gesture command, another unique new Sony function, lets drivers jump to commands with one touch on the display, eliminating the need to dig down on the menu. If drivers want to go home, they just draw a roof (or inverted V) and the destination becomes home. Other gesture commands include zoom in or out, call home and two user-customized destinations. It’s easy to use.
