Product Description

Take your onboard communication and vessel visibility to the next level with the Garmin Signal™ VHF 400 Marine Radio. This advanced fixed-mount VHF radio combines powerful marine communication, Class D Digital Selective Calling (DSC) and an integrated Class B SOTDMA AIS transponder in one compact unit.

Unlike an AIS receiver-only radio, the VHF 400 can both transmit and receive AIS information. This allows your vessel to broadcast its position and navigational information to other AIS-equipped vessels while also receiving information about surrounding marine traffic.

Featuring a bright 3.5-inch colour touchscreen, built-in GNSS receiver, adaptive noise cancellation and VHF audio playback, the Garmin Signal VHF 400 is designed to make communication clearer and improve situational awareness on the water.

With NMEA 2000 and Garmin BlueNet™ connectivity, integrated Wi-Fi and support for compatible remote stations, the VHF 400 offers a modern communication solution for recreational boat owners and professional marine operators.
