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 autoG-PILOT 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 qualified boat builder.
Using the G-PILOT 3380 system :
The G-PILOT 3380 system 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 3380 system is not intended for use in extreme weather, in adverse conditions or
in water near other boats, dangerous waters or land.
The G-PILOT 3380 system 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 3380 system and be ready to resume steering
the boat manually.
The performance of the G-PILOT 3380 system can be affected by the failure of a part,
environmental conditions, improper installation and use.

6 NAVMAN G-PILOT 3380 System Installation Manual
1-2 Using the G-PILOT 3380 system with other instruments
1-2-1 Using other instruments
The G-PILOT 3380 system 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 3380 system for
the G-PILOT to operate in GPS mode (see the
G-PILOT 3380 Operation Manual).
Note: GPS must be via NMEA input.
WIND: A wind instrument, such as a
Navman WIND series, must be connected
to the G-PILOT 3380 system for the G-PILOT
to operate in WIND mode (see the G-PILOT
3380 Operation Manual).
SPEED: A speed instrument, such as:
Navman’s SPEED with a paddlewheel
speed sensor
or a GPS or chartplotter, such as
Navman’s TRACKER 5000 or TRACKFISH
6600 series can be connected to the
G-PILOT 3380 system 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 3380 system is connected to
an instrument with a paddlewheel sensor
and to a GPS, then the G-PILOT 3380 system
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 NavBus
group (see NavBus group in the Setup >
Comms menu, in the G-PILOT 3380 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
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 3380 system
The G-PILOT 3380 system will automatically
work with additional G-PILOT 3380 displays
or G-PILOT 3100 displays.
The G-PILOT 3380 system can receive wind
data from Navman’s WIND over NavBus.
The G-PILOT 3380 system can receive speed
data from Navman’s SPEED over NavBus.
1-2-3 NMEA
NMEA is an industry standard, but is not as
flexible as NavBus as it requires dedicated
connections between instruments. The
G-PILOT 3380 system has one NMEA input port
and one port that can be configured to be an
input or an output (See G-PILOT 3380 Operation
Manual).
G-PILOT 3380 system NMEA inputs
GPS: The G-PILOT 3380 system 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 3380 system 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.

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 3380 system is connected
to a Navman series wind or speed instrument
using NavBus, then the G-PILOT 3380 system will
automatically receive and use the wind or speed
data, and the NMEA connection need not be wired.

3-2 Installation guide
This is a general guide for locating and wiring the parts of the G-PILOT 3380 system. The instructions
for a particular part may have additional requirements.
3-2-1 Location guide
Do not mount any part where it can be
used as a handhold, where it will interfere
with the operation of the boat or where it
might be submerged.
Do not mount any part where it will
interfere with launching or retrieving
the boat.
Do not mount any part within 0.5 m (20”)
of the plane of a radar antenna.
Mount the compass and gyro:
At least 1 m (3 ft) away from sources
of electrical signals or noise, such as
the batteries, high-current cables,
other boat cables, engines, fluorescent
lights, power inverters, radio or radar
transmitters and antennas.
At least 1 m (3 ft) away from equipment
containing a magnet, such as a compass
or speaker.
3-2-2 Wiring guide
The G-PILOT 3380 system 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 3380 system 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 fit more than
one extension cable to each unit.
When fitting any type of cable:
Do not crush, pinch or strain the cable.
Secure the cable at regular intervals.
