  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.
  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.
10.2  Downloading Satellite Data via QuickGPS
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.
To open QuickGPS
On the TouchFLO D Home screen, slide to the AT&T tab, tap the Tools icon 
 , 
then tap QuickGPS.
