Here are some Garmin autopilot systems that are compatible with Garmin chartplotters like the ECHOMAP™ Ultra 2 when connected over a NMEA 2000® network — allowing the chartplotter to engage and control the autopilot:
✅ Compatible Garmin Autopilot Systems
• Garmin Reactor™ 40 Autopilot Series
A modern hydraulic autopilot system offering responsive control, Shadow Drive™ technology, and integration with Garmin chartplotters for course holding and route-following functions. It works over NMEA 2000 and can be controlled from the chartplotter screen.
• Garmin GHP™ 10 Marine Autopilot System
A traditional autopilot package that includes a course computer and control unit. It connects via NMEA 2000 and can interface with a Garmin chartplotter to share heading and control data.
• Garmin GHP™ 12 Autopilot System (Discontinued but historically supported)
Used primarily on sailboats with linear steering drives, this system also works over NMEA 2000 and can interface with chartplotters for autopilot control. 🔧 Control Units (Helm Displays)
Often paired with autopilot systems, Garmin makes control displays like the GHC™ 20 or GHC™ 50 Marine Autopilot Control Unit, which can also be part of a full autopilot setup and share NMEA 2000 data with the chartplotter.
📌 Key Points for Integration
-
The ECHOMAP Ultra 2 supports NMEA 2000, which is required for autopilot integration.
-
With a compatible autopilot and proper wiring/networking, you can control autopilot functions directly from the chartplotter.
-
Installation by a marine professional is recommended to ensure all sensors (heading, rudder feedback, etc.) and steering hardware are properly configured.
