Garmin's nüvi 255W improvesupon its 200-series predecessors by adding top-of-the-line features such as FM traffic updates or MSN Direct content to an entry-level line. But Garmin is also introducing some significant improvements with this new series, like a predictive technology that provides faster satellite lock, a redesigned screen with more information, terrain maps, and an exciting new photo navigation feature. The 255W adds complete maps for North America and Text-to-Speech, so you get turn by turn spoken directions with the real names of streets (e.g. "turn left in 50 feet at Nebraska Way", rather than merely "turn left in 50 feet"). The 255W also offers a wide 4.3-inch (diagonal) screen that displays 70% more of the road around you.
