Cellular Weather
Cellular weather provides data through wireless service providers. An
antenna, such as the Garmin GDL ® 40, communicates with nearby cellular
towers to receive the weather data. The weather data for each feature
comes from reputable weather data centers such as the National Oceanic
and Atmospheric Administration (NOAA) National Weather Service,
Environment Canada, and Météo-France.
To view cellular weather, you must initially select an annual subscription
service online at http://my.garmin.com . You may purchase a day pass directly
from the chartplotter. A day pass provides 24 hours of continuous weather
data. Refer to the antenna installation instructions or the instructions at
http://my.garmin.com to activate this service.
XM WX Satellite Weather
A Garmin XM satellite weather receiver and antenna receives XM WX
Satellite Weather data and shows it on various Garmin devices, including the
Navigation chart on a chartplotter. The weather data for each feature comes
from reputable weather data centers such as the National Weather Service
and the Hydrometeorological Prediction Center. For more information, go to
the XM WX Satellite Weather Web site at www.xmwxweather.com .
To view XM WX Satellite Weather information, you must have a
