Important
It is the owner’s sole responsibility to install and use the instrument and transducer/s in a manner
that will not cause accidents, personal injury or property damage. The user of this product is
solely responsible for observing safe boating practices.
The choice, location, and installation of all components in any autopilot system is critical. If
installation is not correct, the unit can not perform at its designed potential. If in doubt, consult
your Navman dealer. Ensure that any holes that cut are in a safe position and will not weaken
the boat's structure. If in doubt, consult a qualifi ed boat builder.
Using the G-PILOT 3100:
The G-PILOT 3100 is intended as an aid to save a helmsman from having to steer for long
periods of time, not as the main means of steering the boat.
The G-PILOT 3100 is not intended for use in extreme weather, in adverse conditions or in
water near other boats, dangerous waters or land.
The G-PILOT 3100 can not control the boat better than a helmsman. In adverse conditions
steer the boat manually.
Never leave the helm unattended. Keep a watch at all times. The helmsman should always
monitor the course of the boat and the G-PILOT 3100 and be ready to resume steering the
boat manually.
The performance of the G-PILOT 3100 can be affected by the failure of a part,
environmental conditions, improper installation and use.

1-2 Using the G-PILOT 3100 with other instruments
1-2-1 Using other instruments
The G-PILOT 3100 can use data from these
instruments:
GPS: A GPS or chartplotter, such as a
Navman TRACKER 5000 series chartplotter
must be connected to the G-PILOT 3100 for
the G-PILOT 3100 to operate in GPS mode
(see the G-PILOT 3100 Operation Manual).
Note: GPS must be via NMEA input.
WIND: A wind instrument, such as a Navman
WIND 3100 series, must be connected to
the G-PILOT 3100 for the G-PILOT 3100 to
operate in WIND mode (see the G-PILOT 3100 Operation Manual).
SPEED: A speed instrument, such as:
Navman’s SPEED 3100 with a
paddlewheel speed sensor
or a GPS or chartplotter, such as
Navman’s TRACKER 5000 series
chartplotter can be connected to the
G-PILOT 3100 to increase steering
accuracy.
Note: The speed from a paddlewheel
sensor is the speed that the boat is moving
through the water. The speed from a GPS
is the speed over the ground. If there is a
water current then these two speeds will be
different. If the G-PILOT 3100 is connected
to an instrument with a paddlewheel sensor
and to a GPS, then the G-PILOT 3100 will
automatically use the speed from the
paddlewheel sensor instrument.
1-2-2 NavBus
NavBus is a Navman proprietary system that
allows systems of multiple instruments to be
built using a single set of transducers. When
instruments are connected by NavBus:
If you change the units, alarms or
calibration in one instrument, then the
values will automatically change in all
other instruments of the same type.
Each instrument can be assigned to a
group of instruments, called a backlight
group (see BKL GROUP in the FACTORY
menu, in the G-PILOT 3100 Operation Manual). If you change the backlight in an
instrument in group 1, 2, 3 or 4 then the
backlight will automatically change in the
other instruments in the same group. If
6
NAVMAN
you change the backlight in an instrument
in group 0 then no other instruments are
affected.
If an alarm sounds, mute it on any
instrument which can display that alarm.
For more information, refer to the NavBus
Installation and Operation Manual. Note: GPS
must be via NMEA input.
NavBus and the G-PILOT 3100
The G-PILOT 3100 will automatically
work with additional display units.
The G-PILOT 3100 can receive wind data
from Navman’s WIND 3100 over NavBus.
The G-PILOT 3100 can receive speed
data from Navman’s SPEED 3100 over
NavBus.
1-2-3 NMEA
NMEA is an industry standard, but is not as
fl exible as NavBus as it requires dedicated
connections between instruments. The GPILOT has one NMEA input port and one
port that can be configured to be an input
or an output (See G-PILOT 3100 Operation Manual).
G-PILOT 3100 NMEA inputs
GPS: The G-PILOT 3100 can receive
NMEA GPS data from a compatible GPS or
chartplotter, such as Navman’s TRACKER 5000
series chartplotter:
XTE (from APA, APB or XTE sentences)
is required for the G-PILOT to use GPS
mode
BRG (from APA sentences) and BOD
(from APA or APB sentences) are optional
and improve performance
COG (from VTG sentences) is optional
and can be displayed.
WIND: The G-PILOT 3100 can receive NMEA
wind data from a compatible wind instrument:
True or apparent wind direction (from
MWV sentences) is required for the
G-PILOT to use Wind mode.
SPEED: The G-PILOT 3100 can receive NMEA
speed data from a compatible paddlewheel or
GPS instrument:
SOG (from VTG sentences) is optional
and improves performance.
Note: If the G-PILOT 3100 is connected to a
G-PILOT 3100 Installation Manual
Navman 3100 series wind or speed instrument
using NavBus, then the G-PILOT 3100 will
automatically receive and use the wind or
speed data, and the NMEA connection need
not be wired.
(see NMEA 2 DA T in the F ACTOR Y menu, See
G-PILOT 3100 Operation Manual).

At least 1 m (3 ft) away from equipment
containing a magnet, such as a
compass.
3-2-2 Wiring guide
The G-PILOT 3100 has two kinds of cables:
The heavy-duty power supply and steering
drive usually require high-current cables:
Select the wire gauge from the wire size
table (see section 3-4-2).
Fit high-current cables at least 1 m (3
ft) away from other electronic devices in
the boat.
Keep the cables as short as possible.
Twin 2 mm (#14) cable is supplied with the
G-PILOT 3100 and can be used for the high
current cable if its gauge is suitable.
All the other cables are low-current:
Fit low-current cables at least 1 m (3 ft)
away from sources of electrical signals
or noise, such as the high-current cables,
other boat cables, engines, fluorescent
lights, power inverters and radio or radar
transmitters and antennas.
If the cable for the rudder feedback unit,
compass or gyro is too long, do not shorten
the cable; instead coil the cable up near the
main control unit.
The cable for the rudder feedback unit,
compass or gyro can be extended by
adding a 10 m (33 ft) extension cable and
coupling connector. Do not fi t more than
one extension cable to each unit.
