Weather Data Broadcasts

Satellite weather data is broadcast at set intervals. For example, XM weather
radar data is broadcast at five-minute intervals. Cellular weather data is
broadcast at fifteen-minute intervals. When the Garmin receiver is turned on,
or when a different weather 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 different feature appears on the chart.

centered around your current location.
