Garmin 30a 사용자 매뉴얼

The GXM 30A 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 

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 

 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 30A has to receive new data before 

it can be shown. You can experience a delay before weather data 

or a new feature appears on the map.
