Using XM WX Weather and Audio

In order to use XM WX Weather, you must have a Garmin XM WX weather receiver and an
activated XM weather subscription. To use XM Audio, you must have a Garmin XM audio receiver
and an XM Audio subscription. Visit
connect the XM antenna and receiver and for subscription instructions, refer to the Owner's Manual
for your XM equipment.
If you do not have a receiver and a subscription to XM WX Weather, the weather features described
in this section work only when the chartplotter is in Simulator mode. Simulator mode does not
supply live weather data.

Using XM WX Weather

The Garmin XM receiver receives XM WX Weather data and shows it on your chartplotter's
Navigation chart and other screens throughout the device. 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
weather.xmradio.com/weather
NOTE: 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. For example, NEXRAD (NEXt Generation Weather
RADar) data is broadcast at five minute intervals. When the Garmin receiver is turned on or when a
new feature is selected, the receiver has to receive new data before it can be shown.
NOTE: You might experience a delay before weather data or a new feature appears on the map.

shows very light rain and snow up to strong thunderstorms in varying shades and colors. The time

Service last updated the information. You can view NEXRAD information as an image of the latest
