The Garmin Signal™ VHF 400 is a compact, fixed-mount VHF radio designed for recreational and professional mariners. Featuring integrated GPS and AIS transponding capabilities, it delivers reliable two-way communication with exceptional clarity in coastal and offshore waters. Built with a rugged, waterproof design, this radio withstands harsh marine environments whilst maintaining consistent performance. The intuitive interface allows quick access to essential functions, including distress calling, weather alerts, and vessel tracking. With dual-watch capability and programmable channels, you can monitor multiple frequencies simultaneously. The integrated speaker and microphone system ensures clear communication even in challenging conditions. Perfect for cruising, fishing, or commercial operations where dependable VHF connectivity is essential.
Quickly transmit a distress signal to nearby vessels with the distress button, which uses Class D DSC to automatically send crucial information that can help emergency responders. You can also use the intuitive DSC features to quickly initiate contact with other AIS-equipped vessels - simply select the vessel on the AIS plotter view, and call them with a tap of a button.
Configure the radio, program the MMSI number, and get over-the-air software updates with the Active Captain App via built-in Wi‑Fi® connectivity.
Installation is simple since VHF/DSC/AIS features only require a single VHF antenna and the GPS antenna/receiver is built into the unit. Chartplotter integration is seamless via the NMEA 2000® network and Garmin BlueNet™ Network.

ADAPTIVE NOISE CANCELLATION
Advanced noise cancellation uses machine learning algorithms to eliminate wind, wave and engine noise for our cleanest audio experience.
AUTOMATED SQUELCH
Radio activity is constantly monitored to eliminate unnecessary noise and static. You also have the option for manual fine-tuning.
ADVANCED WATCH MODES
All VHF channels are continuously scanned for activity in the background, allowing you to maintain watch over channel 16 and all your favourite preset channels simultaneously.
