•The GPS signal cannot pass through solid non-transparent objects. Signal reception may be affected by obstructions such as high-rise buildings, tunnels, bridges, forests, weather (rainy or cloudy days), etc. If the vehicle’s visor contains metal, it will be difficult for the GPS signal to pass through.

•The Global Positioning System (GPS) is built and operated by the US Defense Department. The Department is responsible for the accuracy and maintenance of the system. Any changes that the Department makes may affect the accuracy and function of the GPS system.

9.3  Downloading Satellite Data via QuickGPS

Before using the phone for GPS navigation, open QuickGPS to download ephemeris data (current satellite position and timing information). QuickGPS significantly speeds up the time for determining your GPS position. QuickGPS downloads ephemeris data from web servers, instead of from satellites, using your phone’s Internet connection via Wi-Fi, ActiveSync or 3G/GPRS/EDGE.

To open QuickGPS

Select Start > QuickGPS.

To download GPS data

Select Download on the QuickGPS screen.

On the screen, initially, you will see the Valid time of the downloaded data. As time passes, the remaining days and hours of validity will be shown.

To speed up GPS positioning, download the latest ephemeris data when the validity of the data expires.
