Introduction  
Warnings  
The GHP™ 10/10V autopilot system  
continuously adjusts the steering of your  
boat to maintain a constant heading.  
In addition to the basic heading-hold  
functionality, the GHP 10/10V autopilot  
system allows manual steering and  
several modes of automatic-steering  
functions and patterns.  
You are responsible for the safe  
and prudent operation of your  
vessel. The GHP 10/10V is a tool  
that will enhance your capability  
to operate your boat. It does not  
relieve you from the responsibility  
of safely operating your boat.  
Avoid navigational hazards and  
never leave the helm unattended.  
Operate the GHP 10/10V autopilot  
system using the GHC™ 10 control unit.  
Through the GHC 10 control unit, you  
engage and steer, set up, and customize  
the GHP 10/10V autopilot system.  
Always be prepared to promptly  
regain manual control of your boat.  
Learn to operate the GHP 10/10V  
on calm and hazard-free open  
water.  
To install the GHP 10/10V autopilot  
system, including the GHC 10 control  
unit, use the provided installation  
instructions.  
Use caution when operating the  
GHP 10/10V at high speeds near  
hazards in the water, such as docks,  
pilings, and other boats.  
The GHP 10/10V and the  
GHC 10 are NMEA 2000®  
certified.

Using Pattern Steering  
The autopilot can steer the boat in preset  
patterns for fishing, and can also perform  
other specialty maneuvers such as  
U-turns and man-overboard retrieval.  
Use the GHC 10 to begin pattern  
steering.

Man Overboard  
The Man Overboard pattern  
Circles  
turns the boat around with the  
intent of running alongside the  
point where the Man Overboard pattern  
was initiated. The boat must be below  
planing speed when using this pattern.  
The circle pattern steers the  
boat in a constant circle, in a  
specified direction and at a  
specified time interval. The default value  
create a circle that takes 5 minutes to  
complete.  
CAuTIoN: The Man Overboard  
pattern is not determined by GPS and  
is affected by wind, current, and speed.  
Be ready to adjust the throttle and take  
the helm to avoid harm to a person in  
the water.  
The autopilot positions the boat so that  
the circle pattern is centered on the point  
at which you engage the pattern.  
GHC 10 Quick Start Manual  
 
     
To begin a GPS pattern:  
1. Begin navigating to a waypoint on  
your GPS device.  
Using GPS Steering  
The autopilot can steer the boat along a  
route defined by your GPS device, or in  
preset patterns based on a GPS location  
(waypoint). To use GPS steering, you  
must have an optional GPS device  
connected to the autopilot. For more  
information on connecting an optional  
GPS device, see the GHP 10/10V  
Installation Instructions.  
2. From the Heading screen, select  
Menu > GPS Steering and choose a  
GPS pattern.  
3. Select Engage to begin the GPS  
pattern with the default settings.  
OR  
Select Setup to adjust the settings for  
the GPS pattern (if available).  
The GPS steering patterns are based on a  
GPS waypoint to which you are actively  
navigating using your optional GPS  
unit. This waypoint is called the active  
waypoint. For example, when you begin  
a Search GPS pattern, the autopilot first  
drives your boat to the active waypoint  
and then circles the active waypoint in a  
spiral pattern.  
4. Choose the direction of the pattern if  
prompted.  
NoTe: If the pattern has only one  
setting, the setting name appears  
instead of Setup. If no settings are  
available for the pattern, Setup will  
not be available.  
CAuTIoN: You are responsible for  
the safe operation of your boat. Do not  
begin a GPS route or a GPS pattern  
until you are certain that the water is  
clear of obstacles.  
To cancel a GPS steering pattern, you  
can physically steer the boat, use the soft  
keys to manually adjust the heading, or  
press the STBY button.

Orbit  
Search  
The Orbit GPS pattern steers  
the boat in a continuous circle  
around the active waypoint.  
The Search GPS pattern steers  
the boat in increasingly larger  
circles (a spiral pattern)  
The size of the circle is defined by your  
distance from the active waypoint when  
you begin the Orbit GPS pattern. There

outward from the active waypoint. When  
you begin the Search GPS pattern, the  
autopilot drives the boat to the active  
waypoint and then begins the pattern.  
The default setting spaces the circles  
20 m apart.  
Cloverleaf  
The Cloverleaf GPS pattern  
steers the boat to repeatedly  
pass over an active waypoint.  
When you begin the Cloverleaf pattern,  
the autopilot drives the boat toward the  
active waypoint and then begins the  
Cloverleaf GPS pattern when  
appropriate. The default settings create a  
cloverleaf pattern that turns the boat at a  
range of 300 m from the active  
waypoint.  
Route To  
The autopilot steers the boat according  
to a route defined on your Garmin  
chartplotter or other compatible  
GPS device.  
To follow a GPS route:  
1. On your chartplotter or GPS device,  
create a route and begin navigating  
the route according to the directions  
provided with the chartplotter or the  
GPS device.  
2. On the GHC 10, from the Heading  
screen, select Menu > GPS Steering

User Settings  
Though the autopilot is configured for  
your boat during installation, you may  
find it necessary to adjust it slightly  
depending on sea conditions. You may  
also disable the Shadow Drive if you  
prefer.  
Shadow Drive Sensitivity—on a  
GHP 10 autopilot system, adjust this  
setting if the Shadow Drive is being  
tripped falsely or not activating properly.  
If the autopilot disengages while the  
helm is steady, decreasing this value  
may help. If the Shadow Drive does not  
disengage the autopilot correctly when  
you take the helm, increasing this value  
may help. This setting does not apply to  
a GHP 10V autopilot system.  
To access the user autopilot  
configuration, select Menu > Setup >  
User Autopilot Configuration.  
Shadow Drive—disable or re-enable  
the Shadow Drive.  
Sea State Filtering—adjust this setting  
to slow the heading response down  
and reduce rudder activity. Leave this  
setting at 0% under normal operating  
conditions, and increase it when  
operating the autopilot in choppy seas  
at low speeds. Increasing the Sea State  
Filtering setting in choppy conditions  
will save wear on your autopilot system.  
CAuTIoN: On a GHP 10 autopilot  
system, if you disable the Shadow  
Drive, you will need to place the  
autopilot on standby (STBY) to  
manually control the helm. Use  
caution when disabling the Shadow  
Drive.
