1  Using GPS

Before you start to use 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 ActiveSync or GPRS. 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 to be  days. As days and time pass, the remaining days and time 

of validity will be shown.

To speed up GPS positioning, download the latest Ephemeris data 

when the validity of the data expires.
