Garmin last-generation communication systems feature innovative design, sturdy and compact. They provide standard Class D DSC functionality (distress calling and direct calling with user programmed MMSI). Just plug and play via the NMEA 2000 network to compatible Garmin chartplotters and MFDs for a real onboard integrated system. The VHF 210i AIS radio displays AIS (Automatic Identification System) on the chartplotter to enhance communication, situational awareness and collision avoidance between you and other mariners.
