Garmin Signal VHF 400 with AIS Transponder

Garmin Signal VHF 400 with AIS Transponder is a premium marine radio designed for active boaters and anglers who want to combine safety, modern connectivity, and clear user-friendly operation in one complete system. The integrated Class B AIS SOTDMA transponder helps you constantly monitor surrounding traffic and improves situational awareness both offshore, in archipelagos, and along busy waterways. The modern 3.5-inch color touchscreen, adaptive noise reduction, and versatile networking capabilities make the Garmin Signal VHF 400 an excellent choice for boats where ease of use and reliable communication are valued in all conditions. Integrated AIS Transponder Enhances Safety on the Water The Garmin Signal VHF 400 features an integrated AIS transmitter and receiver that displays the position, course, speed, and potential encounters of nearby AIS-equipped vessels. This simplifies navigation and helps you make safer decisions, especially in poor visibility and high-traffic areas. Class D DSC emergency functions allow you to quickly send distress calls with a single button press, while AIS integration enables direct communication with selected vessels directly from the chartplotter view. Clear Touchscreen and Intelligent Noise Reduction The streamlined all-in-one design includes an edge-to-edge 3.5” IPS color touchscreen that remains easy to read even in bright sunlight. The adaptive noise reduction uses machine learning algorithms to filter out wind, engine, and wave noise, delivering clearer audio even in demanding conditions. With VHF audio replay, you can replay radio messages up to three minutes long if something was missed or difficult to hear during a busy situation. Extensive Networking and Remote Features The Garmin Signal VHF 400 integrates seamlessly with NMEA 2000® and Garmin BlueNet networks. Wireless software updates and settings management are easily handled through the ActiveCaptain® app using Wi-Fi connectivity. The unit also supports RM 100 Remote Stations, allowing VHF, DSC, and AIS functions to be controlled from locations such as a flybridge or secondary helm station.
