Using GPS with Map Software
You can use the GPS feature of your phone to
provide approximate location data to a laptop
computer or similar device that is running interactive
map software such as that made by DeLorme or
Microsoft. This way, if your phone has good access
to GPS signals, your approximate position on a map
can be made available as you travel in a vehicle.
To do this, connect your phone to your laptop (or
other device) with a data cable and set your phone
to transmit data (see "Getting Started" on page 74).
Your phone then provides your approximate location
to the device running the map software, which
displays your location on a map. Your phone
provides an updated location every second and the
map software displays your changing location on its
See "Enhancing GPS Performance" on page 70
for more details on obtaining good location
Note: Because your phone is continuously
determining your location, using the GPS
feature of your phone with map software
uses the phone's battery power quickly.
Your phone sends location information to your
laptop or other device using the standard National
Marine Electronics Association (NMEA) format.
Your phone supports output messages in
NMEA-0183 format and supports the following
NMEA-0183 sentences: GGA, GLL, GSA, GSV,
RMC, and VTG.
The map software running on your laptop or other
device must support NMEA 3.0.
