Garmin Signal VHF 400 Marine Radios with Built-in AIS Transponder

The Garmin Signal VHF 220 and 400 are premium marine radios designed to help boaters stay connected, informed, and safer on the water. Built with a modern 3.5 inch color touchscreen display, it delivers an intuitive user experience while taking up minimal space at the helm. For sailors and cruisers who depend on reliable communication, the VHF 220/400 combines advanced VHF radio performance with an integrated Class B AIS responder/transponder, allowing you to see and be seen by other AIS equipped vessels in busy waterways and offshore passages.

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

VHF 400 AIS Transponder or VHF 220 AIS Receiver
Maintain situational awareness with the built-in Class B AIS SOTDMA receiver.

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 favorite 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.
