Signal™ RM 100 - VHF remote station

The Garmin Signal™ RM 100 is a remote station designed to extend control of the Garmin Signal™ VHF 400 and VHF 220 marine VHF radios. It allows all functions of the main VHF to be managed from a secondary helm station or flybridge.

The Signal™ RM 100 remote station features a 3.5-inch color touchscreen with an edge-to-edge glass design, delivering a modern aesthetic and seamless integration.

No, the Garmin Signal™ RM 100 is a remote station. It cannot operate without being connected to a main Garmin Signal VHF 400 or VHF 220 unit.

The Signal™ RM 100 remote station provides full control of VHF functions, Digital Selective Calling (DSC), and Automatic Identification System (AIS) from a secondary station.

The display allows you to view and control the various functions of the VHF, including ASN data, AIS information, radio settings, and system alerts.

The Garmin Signal™ RM 100 remote station is compatible with the Garmin Signal VHF 400 and Garmin Signal VHF 220 main units.

The Garmin Signal™ RM 100 uses Garmin BlueNet™ network technology to connect directly to the Garmin Signal VHF 400/220 main unit or via an existing Garmin BlueNet network on your boat.

Yes, the RM 100 remote station is compatible with Garmin Marine Network devices. However, if your boat is equipped solely with these devices, you will need to use a Garmin Marine Network adapter cable (part number 010-12531-01, sold separately) to connect it to the network.

Yes, if your boat is equipped with a Garmin BlueNet™ chartplotter, you can connect the VHF main unit and the RM 100 remote stations to the network ports or to a Garmin BlueNet 20 switch using Garmin BlueNet cables.

Yes, the RM 100 remote station can connect to the ActiveCaptain application. This connection is required to program the VHF with the vessel details and MMSI number, as well as for software updates.

When choosing the mounting location, consider the following:

Avoid extreme temperatures.
Respect the safe distance from the compass.
Mount the microphone within easy reach.
Ensure the location is not obstructed by metal objects that could interfere with the microphone's wireless connection.
Allow approximately 115 mm (4 1/2 in) of space behind the mounting surface for cables.
If exposed to water, mount the device at less than 45 degrees from the horizontal plane and add a drip loop to the cables.

Allow at least approximately 115 mm (4 1/2 in) of space behind the mounting surface to minimize stress on cables and connectors at the rear of the unit.

The RM 100 station is powered via a combined power and audio cable. The red wire must be connected to the positive power source (+) via a manual switch or ignition switch, and the black wire to the negative terminal (-) of the battery or to ground. A 10 A, 32 V fuse (blade type) must be installed on the red wire.

The RM 100 remote station is designed to be compatible with existing cutouts in certain Garmin VHF radios. A retrofit kit (sold separately) can be used to adapt the installation, particularly for replacing Garmin VHF 210/215 or VHF 110/115 radios. Templates may be required to enlarge certain cutouts.

The warranty may be void if the device is not installed in accordance with the instructions, if it is exposed to extreme temperatures outside the specified range, or if the power cable is connected without the appropriate fuse in place.

The bail-mount kit and the retrofit kit for existing cutouts are sold separately. An external speaker and a Garmin Marine Network adapter cable (if required) are also optional accessories.

The Garmin Signal™ RM 100 remote station is designed to operate exclusively with the Garmin Signal™ VHF 400 and VHF 220 marine VHF radio main units. It requires a connection to one of these units to function and cannot operate autonomously.

For a flush-mount installation, allow approximately 115 mm (4 1/2 inches) of space behind the mounting surface to minimize stress on cables and connectors. The mounting surface must be sufficiently robust to support the unit’s weight and protect it from excessive vibration. The unit can also be bracket-mounted; a kit is sold separately.

Mount the unit at less than 45 degrees from the horizontal plane if the location may be exposed to water, to prevent water accumulation near connectors. It is also advisable to add a drip loop to all connected cables to prevent damage to the unit.

For power, the red wire must be connected to the power source (+) via a manual switch or ignition, and the black wire to the battery’s negative terminal (-) or ground. A suitable fuse (10 A, 32 V blade type) must be installed.

The remote station connects to the Garmin VHF 400/220 main unit via the Garmin BlueNet™ network. If your boat is equipped only with Garmin Marine Network devices, a Garmin Marine Network adapter cable (part number 010-12531-01) is required. All Garmin Signal VHF devices must be connected to the same side of the network (BlueNet or Marine Network) to communicate.

The Garmin Signal™ RM 100 is a remote station featuring a 3.5-inch edge-to-edge color touchscreen. It enables full control of VHF functions, Digital Selective Calling (DSC), and Automatic Identification System (AIS) from a secondary helm or flybridge.

It includes intuitive controls with a rotary knob for volume and menu navigation, as well as dedicated buttons for channel 16/D and distress calls. The included remote microphone (fist mic) allows channel switching, transmit power adjustment, and speaker volume control.
