Overview

The Simrad 000-15804-001 is a steer-by-wire autopilot kit for boats running Volvo IPS steering systems. It combines a NAC-D autopilot computer, a Precision 9 compass, and a Volvo Gateway so the autopilot can interface with the IPS steering system while the compass supplies heading and rate-of-turn data for steady course keeping.

This kit makes sense when you want the boat to hold a line on longer transits, during trolling passes, or when you are managing lines and navigation in close quarters. Fit comes down to confirming your boat is truly Volvo IPS steer-by-wire and that your helm electronics are set up to support autopilot control and the required gateway connection.

Compatibility and fit

This kit is intended for vessels equipped with Volvo IPS steer-by-wire steering. Before ordering, verify your drive type is IPS and confirm your steering and helm electronics support an autopilot interface through the Volvo Gateway.

If you are integrating with existing electronics, map out where autopilot control will live at the helm and how heading data will be shared. Taking a few minutes to confirm network and control compatibility up front helps avoid surprises once the boat is apart.

Installation and setup

Plan the component locations with service access in mind. The autopilot computer and gateway are typically mounted inside the helm console or another protected space where they stay dry, wiring can be supported, and connectors are not stressed by vibration.

For the compass, choose a location that stays away from magnetic interference such as speakers, large DC cables, battery banks, and steel structures. A careful compass location is one of the biggest contributors to how well the pilot holds a heading when the sea state and speed change.

On-board use

Once installed and calibrated, this setup helps keep the boat tracking cleanly on longer runs and during repeatable passes, with less constant correction at the wheel. It is a practical match for IPS-powered cruisers and sportfishing boats where steady steering response matters on open-water legs.

Maintenance and care

After the first few trips, recheck mounting fasteners and cable support, then inspect periodically as part of normal seasonal maintenance. Keep connectors clean and strain-relieved, and address any signs of moisture or corrosion early, especially in high-salt environments.
