XM WX WEATHER FEATURES
Displaying Weather Information
The GXM 30 receives XM WX Weather data and shows it on
the Garmin unit’s Map Page and other screens throughout the
unit. The weather data for each feature comes from reputable
weather data centers such as the National Weather Service
and the Hydrometerological Prediction Center. (See the XM
WX Satellite Weather Web site at http://weather.xmradio.
com/weather for more information.) Any weather feature
can change in appearance or interpretation if the source that
provides the information changes. XM WX Weather data is
broadcast at set rates (See page 30 for all weather-related
broadcast rates). For example, NEXRAD Radar data is
broadcast at five minute intervals. When the Garmin unit is
turned on or when a new feature is selected, the GXM 30 has to
receive new data before it can be shown. You may experience a
delay before weather data or a new feature appears on the map.
