Overview
The Garmin 010-01141-00 is a GHC 20 color autopilot control display that mounts at the helm and connects to your NMEA 2000 network for power and autopilot control.
You get a 4 inch QVGA color screen (320 x 240) with a bonded glass lens and anti-glare coating, so it stays readable from different positions at the wheel. There are daytime and night display schemes, plus a dimmer for after-dark running.
For fit planning, the face is about 4.3 x 4.4 inches with about 1.2 inches behind the panel. It is water rated to IPX7, which suits typical helm exposure to spray and washdowns.
Key features
- Helm control head for Garmin autopilot systems on power and sail vessels
- 4 inch QVGA color display (320 x 240) with bonded glass, anti-glare coating, and a 170 degree viewing angle
- Day mode plus night color schemes with adjustable backlight dimming
- Powered through the NMEA 2000 network (LEN 7); supports 9 to 16 VDC supply and operates up to 32 VDC
- NMEA 2000 and NMEA 0183 interfaces for system integration
- ANT wireless support for compatible handheld remote control and quatix watch control
- IPX7 water rating for marine helm installations
Installation and setup
Flush mounting keeps it tidy at the helm and helps protect the connectors behind the panel. Use the gasket and mounting hardware to get an even seal, and leave enough slack for service access and cable bend radius.
On most boats it connects to the NMEA 2000 backbone with a drop cable and T-connector. If you are building a small network for an autopilot, confirm the backbone is powered correctly and terminated at both ends before you start troubleshooting devices.
Compatibility and fit
This control display is used with Garmin autopilot systems, including legacy installations and newer setups. It sits on the same network as the autopilot computer and heading sensor, and it can be finished at the helm with the included trim snap covers to match surrounding Garmin electronics.
Use on board
This is a good match for skippers who want a dedicated autopilot control at the wheel that stays readable in sun and at night, and for boats where you want consistent autopilot control without relying on a chartplotter screen.
