Product details
Garmin Signal™ VHF 400 Marine VHF Radio with Built-in AIS Transponder
Model: 010-02951-00
- Maintain situational awareness with the built-in Class B AIS SOTDMA transponder.
- The included fist mic features a built-in speaker (5-watt RMS) and can be mounted in a different location to the head unit.
- The radio is built to withstand harsh marine environments with an IPX-7 rating.
- Connect a compatible external speaker for more playback options beyond the built-in speaker on the fist mic.
- 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.
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.
The compact and modern design features edge-to-edge glass and takes up minimal space at the helm.
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.
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 ActiveCaptain® smartphone 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.
Advanced noise cancellation uses machine learning algorithms to eliminate wind, wave and engine noise for our cleanest audio experience.
Radio activity is constantly monitored to eliminate unnecessary noise and static. You also have the option for manual fine-tuning.
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.
Didn’t catch that message? Replay it with VHF audio playback, and listen to audio messages for up to 3 minutes on any channel.
