XM WX Satellite Weather

A Garmin XM satellite weather receiver and antenna receives XM WX
Satellite Weather data and shows it on the GPSMAP 640. 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.

Weather Data Broadcasts

Satellite weather data is broadcast at set intervals. For example, XM
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. You might experience a delay
before weather data or a new feature appears on the chart.
