Garmin announced the Garmin Signal™ VHF 400 and VHF 220 all-in-one marine radios designed to help boaters stay connected and aware of their surroundings on the water.
Boasting a revolutionary sleek design, the Garmin Signal VHF radios take up minimal space at the helm and feature an industry-first 3.5-inch colour touchscreen with edge-to-edge glass. The premium Garmin Signal VHF 400 enhances situational awareness by offering an integrated Class B AIS (Automatic Identification System) transponder2, which transmits vessel name, position, course and speed to nearby AIS-equipped vessels.
“When performance and reliability are of utmost importance, the new Garmin Signal VHF radios provide mariners with peace of mind on the water. With a compact, yet modern design, the all-in-one radios offer advanced software features to enable reliable offshore communication when boaters need it most.” Susan Lyman, Garmin Vice President of Global Consumer Sales & Marketing.
World class performance
Leveraging Garmin’s most forward-thinking radio technology into one of the world’s smallest all-in-one marine radios, the Garmin Signal VHF series provides reliability on the water:
- Communicate clearly: Remove unnecessary radio noise with automated squelch and adaptive noise cancellation, which automatically works to tune out background noise, for superior VHF audio clarity when transmitting or receiving voice communication.
- VHF playback: Automatically record up to three minutes of audio transmission from any active channel. The radio can record three different channels simultaneously. Advanced watch modes also allow captains to listen to six channels at the same time for VHF activity.
- Boat-to-boat calling: Transmit a distress signal to nearby vessels with the distress button which uses Class D DSC (Digital Selective Calling) to automatically send crucial information that can help emergency responders. Effortlessly make a DSC call to nearby vessels from the AIS plotter screen.
- Fist mic: Hear audio over engine, wave and wind noise with the included fist mic that features a loud built-in speaker (95 dBA at 0.5 meters), adaptive background noise cancellation and can be mounted in an optimal position, even away from the head unit.
- Simple installation: With the Garmin Signal VHF 400, transmit and receive VHF/DSC/AIS communication from a single VHF antenna2. Includes integrated GPS antenna/receiver, built-in advanced diagnostics tools and support for 12 and 24 V electrical systems.
Radio control away from the helm
Control a Garmin Signal VHF 400 or VHF 220 with the new Garmin Signal RM 100 remote station. The premium fixed-mount head unit allows mariners to connect via the Garmin Marine Network and control radio functions from a secondary helm or flybridge. The intercom feature enables communication between remote station and networked head units. Boasting a modern, edge-to-edge glass design and 3.5-inch colour display, this remote station includes a fist mic to match the look of Garmin Signal VHF marine radios and compliments the helm on any vessel.
Superior system integration and connectivity
The Garmin Signal VHF radios integrate seamlessly with Garmin chartplotters via the NMEA 2000®network, Garmin Marine Network 1.0 and Garmin BlueNet™. They also support connection to a compatible loudhailer for onboard announcements, an external speaker connection for VHF audio at a second location and NMEA 2000 for AIS, DSC, GPS and external heading sensor data.
Captains can configure the radio, program the MMSI (Maritime Mobile Service Identity) number and get over-the-air software updates with the ActiveCaptain® smartphone app with built-in Wi-Fi® connectivity.
