• 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.

• Wireless communication products (such as mobile phones or radar-detecting

devices) may interfere with the satellite signal, resulting in unstable signal

reception.

• 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.

9.2 Downloading Satellite Data via QuickGPS

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

first to download ephemeris data (current satellite position and timing information)

onto your phone. 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 phone, which can be via Wi-Fi,

ActiveSync or GPRS/3G. This significantly speeds up the time for determining your

GPS position.

To open QuickGPS

Click Start > All Programs > Accessories > QuickGPS.
