Garmin’s nüvi 255 W 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”
Important Product Information: This device features a “screen lock” feature. This is a standard feature on all nüvi 2×5 and 7×5 Garmin units. If you slide the “Power” key to the right, it will lock the screen and prevent any accidental touches. Once the screen lock feature is engaged, the screen will go black/gray after about 15 seconds to save power on the device. To unlock the screen, just slide the “Power” key to the center position. This feature is really targeted for “Pedestrian” mode so that a user can put the device in his or her pocket/purse and quickly unlock the screen instead of powering on/off continuously. For more information, see page 5 of the product manual.
Your GPS device locks onto transmissions from a dedicated network of Satellites in order to determine its position. Until the device gets a “lock” on three satellites, it can’t effectively navigate, so decreasing the time it takes for your device to get “satellite lock” is always a goal of GPS manufacturers. With Garmin’s new HotFix technology, your Garmin GPS remembers the position of all satellites it is tracking when you turn it off, and calculates their movements in order to predict where they should be the next time you turn it on. This gives the device an idea of where it should look for satellites, and dramatically decreases the time it takes for your Garmin to get its position and start navigating. HotFix can predict satellite positions for up to 3 days after the device was last turned off.
Using Garmin’s unique Web site — Garmin Connect Photos — users can choose from millions of geo-located photos provided by Google’s Panoramio photo sharing community and download them to the nüvi for a richer navigation experience using pictures as a guide
