YOUR ADVANCED COMMUNICATION SOLUTION - Stay connected and aware on the water with Garmin Signal VHF 400, the marine radio with advanced features and a colour touchscreen display.

BUILT‑IN AIS - Stay aware on the water with built-in AIS transmit and receive capabilities. This feature shows you range, course, speed and the crossing situation of other AIS-equipped vessels around you to help you navigate.

SLEEK DESIGN - The compact and modern design features edge-to-edge glass and takes up minimal space at the helm.

CLEAR AND SIMPLE COMMUNICATION - Eliminate unnecessary radio noise with automated squelch. If you miss a radio message, you can replay it with VHF audio playback. When you need to maintain watch on multiple channels, advanced watch modes make it easy.

STAY CONNECTED - 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.

EASY TO UPDATE - Configure the radio, program the MMSI number, and get over-the-air software updates with the ActiveCaptain^® smartphone app via built-in Wi‑Fi^® connectivity.

INSTALLATION IS A BREEZE - 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.

VHF AUDIO PLAYBACK - Didn’t catch that message? Replay it with VHF audio playback, and listen to audio messages for up to 3 minutes on any channel.

AIS TRANSPONDER - Maintain situational awareness with the built-in Class B AIS SOTDMA transponder.

FIST MIC - The included fist mic features a built-in speaker (5-watt RMS) and can be mounted in a different location to the head unit.

RUGGED DESIGN - The radio is built to withstand harsh marine environments with an IPX7 rating.

EXTERNAL SPEAKER SUPPORT - Connect a compatible external speaker for more playback options beyond the built-in speaker on the fist mic.

HAILER WITH LISTEN BACK - Connect the radio to a compatible loudhailer for broadcasting announcements. The listen back feature gathers background sounds that can be heard through the fist mic or external speaker.
