Will the Garmin Chartplotter Output NMEA 0183 in Simulator Mode?
NMEA 0183 is a communication method that allows marine devices to communicate with each other. It provides transmission of GPS, route, sonar, and additional information between the devices.
Garmin chartplotters manufactured from 2007 and newer cannot output NMEA 0183 data in simulator mode. The device must operate in normal mode to communicate with other devices.
