  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.

  Do not leave your device in a vehicle or expose the device to direct 

sunlight to avoid overheating the battery, which could pose damage 

to the device or risk to the vehicle.

Before you start using your device for GPS navigation, open the QuickGPS 

program first to download ephemeris data (current satellite position and 

timing information) onto your device. This data is needed to determine the 

GPS position of your current location.
QuickGPS downloads ephemeris data from a Web server, instead of from 

the satellites, using the Internet connection on your device, which can be 

via Wi-Fi, ActiveSync or GPRS/G. This significantly speeds up the time for 

determining your GPS position.

Tap Start > Programs > QuickGPS.

Tap 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.
