Garmin Signal™ RM 100 Marine VHF Radio Remote Station

Garmin Signal™ RM 100

The Garmin Signal RM 100 is a premium fixed-mount remote station designed to extend the capabilities of your compatible Garmin Signal VHF marine radio to a secondary helm or flybridge. With a single Garmin BlueNet Network connection, installation is clean and straightforward, giving you full remote access to VHF, DSC, AIS, and other radio functions without complex wiring.

At the heart of the RM 100 is a bright 3.5-inch color IPS LCD capacitive touchscreen display with a resolution of 640 x 480 pixels and a backlight rated at 1,000 nits, ensuring excellent visibility even in direct sunlight. The modern edge-to-edge glass design complements the aesthetic of the Garmin Signal VHF marine radio series, creating a cohesive and professional helm configuration.

The included fist mic features built-in adaptive noise cancellation, delivering superior audio clarity even in high winds or rough seas. The head unit supports up to 15 W RMS external speaker output, while the fist mic provides up to 5 W RMS speaker output. An intercom feature enables two-way communication between the remote station and networked head units aboard the vessel.

The Signal RM 100 supports a wide range of VHF features including dual/tri watch, preset watch channels, NOAA weather alert and watch, audio record and playback, auto squelch, AIS target display, and AIS collision and MOB alarms. A night vision mode is also included for low-light operation. The unit is compatible with the Garmin Signal VHF 220 and Garmin Signal VHF 400 radios.

Built for life at sea, the Signal RM 100 carries an IPX7 water rating and operates across a wide temperature range of −20° to 55°C. It accepts a broad input voltage range of 9.6–32 VDC, making it suitable for both 12 V and 24 V systems.
