Considerations).
If there is not an existing NMEA 2000 network
on your boat, you can build one using the
supplied cables and connectors

System).
CCU
The CCU can be mounted in a non-submerged
location near the center of the boat, in any
orientation
Considerations).
The CCU must be located away from sources of
magnetic interference.
Installation Procedures
Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.
When drilling or cutting, always check what is on the opposite
side of the surface.
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
You must Install the helm control by flush-mounting it in the
dashboard near the helm and connecting it to a NMEA 2000
network.
To use advanced features of the autopilot, optional NMEA 2000-
compatible or NMEA 0183-compatible devices, such as a wind
sensor, water-speed sensor, or GPS device, can be connected
to the NMEA 2000 network or connected to the helm control
through NMEA 0183.
Mounting the Helm Control
If you are mounting the device in fiberglass, when drilling the
four pilot holes, it is recommended to use a countersink bit to
drill a clearance counterbore through only the top gel-coat layer.
This will help to avoid any cracking in the gel-coat layer when
the screws are tightened.
Stainless-steel screws may bind when screwed into fiberglass
and overtightened. Garmin recommends applying an anti-seize
lubricant to the screws before installing them.
Before you can mount the helm control, you must select a
mounting location

1
Trim the flush-mount template and ensure it fits in the
selected mounting location.
The flush-mount template is included in the helm control
product box.
2
Secure the template to the selected mounting location.
3
If you plan to cut the hole with a rotary cutting tool instead of
a 90 mm (3.5 in.) hole saw, use a 10 mm (3/8 in.) drill bit to
drill a pilot hole as indicated on the template to begin cutting
the mounting surface.
4
Using the hole saw or rotary cutting tool, cut the mounting
surface along the inside of the dashed line indicated on the
template.
5
If necessary, use a file and sandpaper to refine the size of
the hole.

1
Hold the ECU in the intended mounting location and mark the
locations of the mounting holes on the mounting surface,

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.
Connecting the ECU to Power
When connecting the power cable, do not remove the in-line
fuse holder. To prevent the possibility of injury or product
damage caused by fire or overheating, the appropriate fuse
must be in place as indicated in the product specifications. In
addition, connecting the power cable without the appropriate
fuse in place will void the product warranty.
You should connect the ECU power cable directly to the boat
battery, if possible. Although it is not recommended, if you
connect the power cable to a terminal block or other source, you
must connect it through a 40 A fuse.
