Garmin 255w GPS
The Garmin 255W GPS comes with "Hot Fix" technology. So what does this mean? Anyone who has used a personal GPS before has experienced the annoyance of waiting for the unit to finish "Acquiring Satellites". This can be especially irritating when coming out of a parking garage and on to busy city streets that are shadowed by huge sky-rise buildings. You're in a hurry to meet your next appointment, you programmed the address into your GPS and off you go - block after block goes by as you blindly drive on and on, anxiously waiting for the device to lock and begin navigating you in the correct direction.
A GPS determines its position by syncing up to signals being transmitted from a network of satellites orbiting the earth. The device can not accurately determine its position until it has acquired (or "locked to") a minimum of 3 of these satellites. The more GPS satellites the unit can lock to, the better the accuracy. Decreasing the time that is required for a GPS device to acquire a satellite lock is one of the major goals of the manufacturer and one that has been greatly improved upon with the Garmin 255W GPS.
With "Hot Fix" technology," lock-time" is significantly reduced. When you power the Garmin 255W GPS off the device saves the position of all the satellites it is tracking and calculates their movement to predict where they should be when you power the GPS device back on. This gives the navigation device a good idea of what satellites to start looking for and where they should be the next time it is turned on - effectively, this dramatically minimizes the time it takes for the Garmin 255W GPS to begin navigating once the power has been turned back on. Satellite position can be predicted for up to 3 days after turning the device off.
