Using XM WX Weather and Audio

In order to use XM Weather, you must have a Garmin GDL 30 or 30A XM receiver and an activated

XM weather subscription. To use XM Audio, you must have the Garmin GDL 30A XM receiver

and an XM Audio subscription. To connect the XM antenna and receiver and for subscription

instructions, refer to the GDL 30/30A Marine Weather Satellite Receiver Installation Instructions.
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 unit is in Simulator Mode.

Using XM WX Weather

The GDL 30/30A receives XM WX Weather data and shows it on your unit’s Navigation chart 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.)

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 unit is turned on or when a new

feature is selected, the GDL 30/30A 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.
