How to Add Wireless Remote Control to Raymarine SeaTalk Autopilots

Controlling a Raymarine SeaTalk autopilot from anywhere on board is now possible without rewiring or replacing existing hardware. Whether you sail with an ST1000, ST2000, ST4000 or ST7000, you can add wireless remote control using a compact plug-in module that connects directly to the existing SeaTalk network, such as the ST Wireless system available on this site.

This guide explains how the system works, what it is compatible with and how easy it is to install.

What Is SeaTalk and Why Add Wireless Control

Raymarine’s original SeaTalk network is reliable but was designed before modern wireless devices. Control is limited to the fixed keypad or tiller unit unless upgraded.

Adding wireless control allows you to:

adjust heading while trimming sails
stay in control when short handed
operate the pilot from the cockpit or foredeck
reduce wear on ageing keypads
use mobile and wearable devices on board

The upgrade does not require replacing the autopilot.

Compatible Raymarine Autopilots

A plug-and-play SeaTalk wireless gateway, such as ST Wireless, can be added to most legacy Raymarine systems, including:

ST1000 and ST2000 tiller pilots
ST4000 and ST4000 Plus
ST5000 and ST6000 series
ST7000 and ST8000 series
Course computer based systems using classic SeaTalk

Owners of newer EV100 and EV200 systems can also add wireless functionality using N2K Wireless, designed for SeaTalk NG and NMEA 2000 networks.

How the Wireless System Works

A compact SeaTalk gateway like ST Wireless connects to the existing red, yellow and black conductors and listens to the network. When paired with a phone or smartwatch, it sends controlled heading adjustments to the autopilot while all original functions remain available.

Control is typically provided through:

iPhone or Android app
Apple Watch or Wear OS
optional handheld remote

The autopilot can always be disengaged using the original keypad or tiller button. No changes are made to calibration or steering settings.

For newer systems using SeaTalk NG or NMEA 2000, N2K Wireless provides the same remote control capabilities through the backbone.

Installation Overview

Installing a plug-in module usually takes less than thirty minutes and does not involve modifying factory wiring.

Tools required:

small screwdriver
access to the existing SeaTalk cable
fuse protection if not already present

Steps:

Locate the SeaTalk wiring near the control head or course computer
Connect the module using the same three conductors
Mount it in a dry, accessible location
Pair the mobile device or watch
Test port and starboard adjustments at the dock
Confirm the original controls operate normally

The upgrade is fully reversible. ST Wireless installs directly on classic SeaTalk, while N2K Wireless connects to the SeaTalk NG or NMEA 2000 backbone.

Safety and Best Practice

When using wireless control:

always keep the original standby button accessible
test the system in calm conditions before passage
ensure the device reconnects safely if signal is lost
use wireless control for course adjustments, not emergency manoeuvres

A suitable gateway sends small, incremental heading changes rather than full helm commands.

SeaTalk NG and Evolution Autopilots

Newer Raymarine EV100 and EV200 systems communicate using SeaTalk NG or NMEA 2000 rather than classic SeaTalk.

Wireless control can be added by installing N2K Wireless, which connects to the backbone and provides the same remote features without altering pilot configuration or affecting warranty. This allows Evolution systems to be controlled from a phone or smartwatch in the same way as older pilots fitted with ST Wireless.

Frequently Asked Questions

Can I use my phone to control a Raymarine autopilot
Yes, when paired with a compatible plug-and-play gateway such as ST Wireless or N2K Wireless. The phone sends controlled heading adjustments while the pilot remains engaged.

Does this work with ST1000 and ST2000 tiller pilots
Yes, using ST Wireless when the pilot is connected to classic SeaTalk.

Do I need to rewire the autopilot
No. The module connects to the existing red, yellow and black wiring without modification.

Can I still use the original Raymarine keypad
Yes. The original controls always take priority and can disengage the autopilot immediately.

Conclusion

Adding wireless remote control to a Raymarine SeaTalk autopilot is a quick, non-invasive upgrade that improves safety, convenience and single handed sailing. A plug-and-play gateway such as ST Wireless keeps the original system intact and brings older pilots up to modern expectations without replacing trusted equipment, while N2K Wireless provides the same benefits for SeaTalk NG and NMEA 2000 networks.
