XM WX Satellite Weather and Cellular Weather Selecting a Cellular or XM Antenna If your chartplotter is connected to both a cellular and an XM antenna, you must select which antenna you want to provide weather service. If you are 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. 1. From the Home screen, select Configure > Communications > NMEA 2000 Setup > Preferred Devices > Weather Antenna. 2. Select an antenna. Selecting an External Cellular Antenna If your chartplotter is connected to an external cellular antenna, you must select that antenna on your chartplotter.
