Garmin Signal VHF 400 Marine VHF Radio w/Built-In AIS Transponder [010-02951-00]

Signal™ VHF 400 Marine VHF Radio with Built-In AIS Transponder

BUILT-IN AIS

Stay aware of 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 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.
