Garmin Signal RM 100 Remote Station for VHF 400 and 220
Garmin Signal RM 100 Remote Station for VHF 400 and 220 — Product description
The Garmin Signal RM 100 puts full VHF control at your second helm. Mount it on the flybridge or a secondary console and run VHF, DSC, and AIS right from a bright 3.5-inch touchscreen. It links to your Garmin Signal VHF 400 or 220 over a single BlueNet cable, and the included fist mic keeps your calls clear when the wind picks up.
If you run a boat with more than one steering station, you already know the problem. You're up on the flybridge, a call comes in on the VHF, and the radio is down at the lower helm. The Garmin Signal RM 100 fixes that. It's a fixed-mount remote station that gives you a full second set of controls for your Garmin Signal VHF radio, so you can talk, monitor, and respond from wherever you happen to be steering that day.
This isn't a stripped-down accessory. From the RM 100 you get remote access to VHF, DSC, and AIS, plus the other functions your Signal VHF radio handles. Distress calling, position reporting, routine channel changes, it's all right here at the second helm. And because the remote station talks to the head unit natively over the network, there's no lag and no clunky workaround. What you'd do at the main radio, you do here.
Setup is genuinely simple. The RM 100 connects to your Garmin Signal VHF 400 or 220 through a single Garmin BlueNet network cable, and Garmin ships a 6-meter run in the box. One cable carries the data, so you're not fishing a bundle of wires through the console. If you've rigged network gear before, you'll have this mounted and talking in an afternoon. The compact head unit and reduced mounting depth help a lot when panel space behind the dash is tight, which on most flybridges it usually is.
The display is the part people notice first. It's a 3.5-inch color IPS touchscreen at 640 by 480 resolution, backed by a 1,000-nit backlight that stays readable in direct sun. The edge-to-edge glass and capacitive touch feel clean and modern, and the form factor matches the Garmin Signal VHF radios, so a helm built around Garmin gear looks like one system instead of a parts bin.
The included fist mic has built-in adaptive noise cancellation, and that matters more than it sounds on paper. When you're running into a headwind or the seas are up, the mic works to strip out the background so the Coast Guard or the marina hears you the first time. There's also an intercom feature that lets the remote station and your networked head units talk to each other, which is handy for calling down to the cockpit without shouting over the engines.
Garmin built the RM 100 for life on the water. It carries an IPX7 water rating, so spray, rain, and the occasional wave over the rail won't kill it. It runs on anything from 9.6 to 32 volts DC, which covers both 12-volt and 24-volt systems. The head unit draws about 400 milliamps at 12 volts, so it stays easy on your battery bank even on a long day out.
Who's this for? Anyone running a flybridge cruiser, a sportfisher with a tower, or a center console with a second station who's tired of missing calls. One thing to know going in, the RM 100 is a remote station, not a standalone radio. It needs a Garmin Signal VHF 400 or 220 as the main head unit to work. If you've already got one of those aboard, or you're planning the install together, this is the clean way to add real control at the second helm.
Open the box and everything you need to rig it is right there. You get the RM 100 head unit, the fist mic, a sun cover to protect the screen when it's parked, the remote station power and external audio cable with an inline fuse, a separate fused power cable for the fist mic, the 6-meter BlueNet network cable, mounting hardware, a mounting template, and the documentation. Garmin includes that template for a reason, so trace it, cut once, and you'll get a clean flush mount on the first try.
