DESC: Sony has mapped its way into the portable GPS market with the NV-U70T. The touch-screen display is 3.5 inches, and has an 80-degree viewing angle. It comes with a “smart cradle” and attaches with a one-touch release suction cup. Sounds like Sony supplied its own GPS chip for the nav-u, and it has a dynamic re-routing capability and can connect to real-time traffic information via TMC (Traffic Message Channel) where available. You won’t have any trouble hearing the nav-u tell you when to “turn left” because it is outfitted with a two-way speaker system that includes a “funky 1.6 Woofer at the back and a Tweeter in the front.
