Installation Procedures
CAUTION
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
NOTICE
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
After you have planned the autopilot installation on your boat and satisfied all of the mounting and wiring
considerations for your particular installation, you can begin mounting and connecting the components.
Helm Control Installation
A dedicated helm control is not included in all autopilot packages. If you install the autopilot without a dedicated
helm control, the autopilot CCU must be connected to the same NMEA 2000 network as a compatible Garmin
chartplotter to configure and control the autopilot system.
Detailed mounting instructions are included in the helm control box.
Mounting the CCU
1 Determine the mounting location.
2 Using the CCU as a template, mark the two pilot hole locations on the mounting surface.
3 Using a 3 mm (
1
/
8
in.) bit, drill the pilot holes.
4 Use the included screws to attach the CCU to the mounting surface.
NOTE: If you use mounting hardware other than the provided screws, the hardware must be quality stainless
or brass material to avoid magnetic interference with the CCU.
Test any mounting hardware with a handheld compass to make sure no magnetic fields are present in the
hardware.
ECU Installation
Mounting the ECU
Before you can mount the ECU, you must select a location and determine the correct mounting hardware (
Mounting and Connection Considerations, page 6
).
1 Hold the ECU in the intended mounting location and mark the locations of the mounting holes on the
mounting surface, using the ECU as a template.
2 Using a drill bit appropriate for the mounting surface and selected mounting hardware, drill the four holes
through the mounting surface.
3 Secure the ECU to the mounting surface using the selected mounting hardware.
