TomTom's versatile GO 910 plug-and-play navigation system offers accurate, turn-by-turn satellite navigation, provides you with a few entertainment options, and even gives you the option of making hands-free phone calls and keeping tabs on traffic conditions along your route. Just turn on the GO 910, punch in a destination using the touchscreen controls, and you're ready to go. The built-in antenna tracks your position continuously, while maps displayed on the vivid 4" screen show you where you're going and voice prompts tell you exactly where to turn.
