Using Assisted GPS (A-GPS)
To enable and disable A-GPS, tap / Settings / System / GPS /
A-GPS. If the GPS has been used in the prior 72 hours, A-GPS will
retain a memory of the satellite paths. The A-GPS satellite data is
stored in memory for the satellites visible in your current position.
Therefore the unit can lock on the satellites quickly, in less than 20
seconds in an open sky. The expiration of the A-GPS data is also
shown in this menu. Using A-GPS may reduce accuracy in some
situations.
If you are unable to connect to the GPS using the default GPS
settings, you can restore it to factory default settings by performing
a system shutdown and leaving the unit shut down for
approximately 5 minutes. See Power key features on page 11.
SatViewer
(Optional on certain device offerings; may not be installed.)
If your unit has the built-in GPS, it may have SatViewer™
installed. External GPS receivers, Bluetooth GPS receivers or other
external GPS devices (including other SiRF II or SiRF III GPS
receivers) are not supported and may not work correctly with
SatViewer. See Appendix A for more instructions on using
SatViewer.
Exiting GPS applications
Any time you exit a GPS application (such as SatViewer) it is
advisable to close the port gracefully, e.g. tap
Disconnect from
GPS
and exit the application. Failure to do so may leave the port
open and hinder the next GPS operation
