connected to only one antenna, that antenna is selected automatically.
If you have both a cellular antenna and an XM antenna connected to your
chartplotter and you select the cellular antenna, XM weather data does not
appear, but your XM radio is still available (if you have a paid subscription).
If you select the XM antenna, cellular weather data does not appear.
