INTRODUCTION
The GEONAV is a chart plotter that can be interfaced with a
GPS receiver, autopilot and other onboard instruments, and
allows displaying the boat’s geographical position with respect
to an electronic chart.
Thanks to the GEONAV and a NAVIONICS electronic chart,
you will never get lost even in case of fog, rain or dark.
The GEONAV, available with either sunlight-readable color
display or sunlight-readable monochrome display, has been
designed to allow flush mounting. Equipped with an easy-to-
use keyboard, the GEONAV allows controlling the autopilot
directly from the plotter (Easy Pilot function) and, thanks to
the unlimited capacity of the new CompactFlash™ cartridges
- that can also be used on PCs as personal hard disks - can
store a large amount of route, track and marker data.
The GEONAV is equipped with three software versions (stan-
dard, advanced and sailing), automatically selected according
to the instrument connected. The connecting supports both
the NMEA 0183 standard protocol and the new NMEA 2000
network, suitable for the network connection of multiple sta-
tions or several instruments of different brands.
The Route functions will allow you to plan a trip, while, thanks
to NAVIONICS electronic charts, you will always know ex-
actly the boat’s position. NAVIONICS charts are available for
all the most popular boating areas and can be used in addition
to official paper charts to obtain additional information, such
as the availability of port services as well as tides and cur-
rents data. NAVIONICS electronic charts are available world-
wide from authorized NAVIONICS dealers.
Should new functions be available in the future, it will be
possible to update the GEONAV internal software at any
NAVIONICS dealer.

INSTALLATION AND PRECAUTIONS
Precautions
To avoid electromagnetic interference, the GEONAV must be
positioned at least 0.72 m (Flash, Sun), 0.50 m (Sunshine 11)
or 0.45 m (Sunshine 8) away from the magnetic compass.
Wherever possible, the power supply cable shield should be
connected to the boat’s ground plate.
The GEONAV is water resistant but not waterproof, and should
not be immersed totally in water.
The cartridge slot cover, located on the plotter’s right-hand
side, should always be kept closed and opened only when
replacing cartridges. Make sure that the cartridge replacement
is carried out as the unit is perfectly dry and that no water
enters the unit.
Rear connectors, when not in use, should always be protected
by the appropriate rubber covers.
Cleaning
It is recommended the use of a non-alcoholic product to clean
the glass, since alcoholic products may damage the glass sur-
face or make it opaque.
Panel mounting
Locate the area where the GEONAV is to be installed, then
use the drilling template supplied with the plotter to properly
cut holes and sockets out of the instrument’s panel.
The neoprene adhesive gasket supplied must be applied to
the GEONAV rear side to avoid moisture penetration and to
reduce vibrations.
Mounting screws must be 4 mm in diameter and maximum 5
mm in length, plus the thickness of the panel. Do not exceed
tightening the screws, in order to avoid damaging the screw
seats.
Installation and Precautions
Characteristics

10 11
Flush mounting
Locate the area where the GEONAV is to be installed, then
use the cutting template supplied with the plotter to cut the
panel.
Apply a layer of silicone glue (the use of black colored glue is
recommended, in order to prevent the area from going yellow
when exposed to sunlight) to the plastic frame rear part; place
the frame into the socket cut out of the panel, so that the
frame edge leans against the panel.
Make sure that the frame and the panel are correctly fixed; if
necessary, apply additional metal brackets (not supplied in
the package) as shown in the figure below.
Let the silicone glue dry, then apply the neoprene gasket to
the plotter rear side, insert the instrument into the frame and
lock it by the screws supplied.
Do not exceed tightening the screws, in order to avoid damag-
ing the screw seats.
Bracket mounting
Fix the bracket to the boat’s dashboard by screws 6mm in
diameter.

Removing the CompactFlash™
Make sure that the plotter is perfectly dry.
Open the cartridge slot cover located on the plotter’s front
side, then extract the cartridge.
WARNING: Always use CompactFlash™cartridges certified by Navionics. The
use of non-certified cartridges may result in improper operation of the unit.
The CompactFlash™ cartridges can be used as a mass-storage
with any PC computer, so can be the cartridge used by the
plotter. However, the plotter needs to find some free space in
the cartridge in order to work properly. Prior to use a new
cartridge, always make sure that there are at least 2.5MB of
free space.
WARNING: Be careful when handling the cartridge files by using the PC. Windows
allows deleting and moving files easily, therefore pay attention when using Windows
Explorer not to erase the content of the \NAVIONIC and \GEONAV folders. Damaging
the files stored in such directories may result in loss of data or improper operation of
the unit.
CARTRIDGE INSTALLATION
Installing the CompactFlash™
Open the cartridge slot cover located on the plotter’s front
side.
Insert the cartridge into the appropriate slot, with the label
side (side with a small arrow) towards the right, and push it
down.
Close the cover exercising light pressure and check that it is
perfectly closed, in order to avoid any water infiltration.
NOTE: Make sure of inserting the cartridge correctly. Should you try to insert the
wrong side of the cartridge, full insertion into the slot is hampered. Any further attempt
to force the cartridge into the slot may damage the cartridge or the plotter. This kind of
damage is not covered by the warranty.

FUNCTIONAL CHARACTERISTICS
This chapter describes some of the most important functions
of the GEONAV, as well as the terms most commonly used in
this document.
Switching on/Switching off the unit
To switch the GEONAV on, press the PWR key. To switch it
off, keep the PWR key pressed for more than 3 seconds.
Welcome page
At start-up, the GEONAV displays a welcome page whose text
(e.g., the boat’s name) can be edited by the Setup menu (see the
Setup Section). To freeze the page displayed, press PAGE. To
unfreeze the page and continue with the instrument’s opera-
tion, press PAGE again.
Standard/Advanced modes
The GEONAV can operate in Standard mode or in Advanced
mode. In Advanced mode, even the less frequently used func-
tions, such as data saving to cartridges and heading/speed
filters, are available. In Standard mode, some menus feature
less options, thus making it easier to use the plotter. To choose
the operating mode desired, press the PAGE key to display the
menu, select SETUP and then SELECT MODE.
Depth sounder
If connected to a depth sounder via NMEA, the GEONAV will
enable the depth sounder mode, showing a graph of the sea
bed or the relevant data in numerical form.
The depth value can be expressed in meters (default value),
feet or fathoms; to select the unit, press PAGE to display the
menu, select SETUP and DEPTH UNITS (M/FT/FA).
Sailing functions

5 - Route leg
Part of route between two waypoints.
6 - Waypoint
Waypoints are identified by a circle and a number. The route
starting point is marked by the “X”symbol. The target waypoint
is identified by a filled circle, whereas the route leg currently
followed is identified by a thicker line.
7 - Cursor
Indicates the position expressed in geographical coordinates
(latitude and longitude).
It is displayed when the plotter is in Cursor mode.
8 - Heading vector
Indicates graphically the boat’s current route.
9 – North indicator
Indicates the north direction when the Chart rotation func-
tion is enabled.
10 – True wind vector
Indicates the direction of true wind detected by onboard in-
struments.
11 – Layline
Indicates the direction after the next tack or gybe. In order to
achieve the best performance, the tack or gybe should be car-
ried out as soon as the layline crosses the target waypoint.

range before activating the chart rotation. Confirm by press-
ing ENTER.
The northern direction will be indicated by the symbol
Autozoom
With the Autozoom function the GEONAV will always display
automatically the boat’s position and the target waypoint at
the best available chart range. This function is enabled pro-
vided that at least one waypoint has been previously entered.
NOTE: In this document, the functions enabled in Advanced and Sailing modes are
outlined in the text. Unless otherwise specified, functions are intended as common to
all the available modes.
Navigation mode (automatic)
At start-up, the GEONAV automatically enables the Naviga-
tion mode, as soon as the GPS transmits a valid fix; when in
Navigation mode:
•The manual cursor is not displayed
•The depth sounder window can be accessed
This mode is also called automatic because the unit automati-
cally updates the boat’s position on the screen.
Cursor mode (manual)
When in Cursor mode, the manual cursor is displayed. It is
possible to insert, delete and move waypoints, insert and delete
markers, display navaid information, etc., but it is not possible
to gain access to the depth sounder window.
To switch from Navigation mode to Cursor mode, use the
joystick. To go back to Navigation mode, press the PAGE key.
Chart rotation
Charts are traditionally displayed in north-up mode. This,
however, does not correspond to reality. For example, when
traveling southwards, the chart shows, on the right side of
the boat, what is actually located on the left side, and vice
versa.
The Chart Rotation function allows rotating the electronic chart
displayed according to the plotted route (COG - Course Over
Ground), as detected by the GPS receiver. Since the COG value
varies continuously, a filter has been inserted to prevent the
chart from bouncing.
The Chart Rotation function is enabled at a speed greater than
1 knot. To enable the Chart Rotation function, press PAGE to
display the menu, select SETUP, then CHART ROTATION
and ON. A message will prompt the user to select the chart

To enable these functions, rotate the knob to display the EBL,
position the line on the bearing desired, then press the knob
to enable the VRM ring and adjust its size by rotating the knob
so as to reach the range desired. To edit the values set, press
the knob to switch from the VRM function to the EBL func-
tion. Press MARK to insert a marker where the EBL and VRM
intersect, and ENTER to insert a waypoint.
Range and bearing values are displayed in the top left-hand
corner of the screen, together with the indication of the func-
tion currently enabled.
Press CLR to disable the two functions in sequence.
The VRM ring can also be used to set the range for navigation
from the coast, for example to avoid navigating out of the limit
allowed. In this case, set the EBL to any value, adjust the
VRM ring size as desired, then navigate making sure that at
least one point in the ring is always touching the coast.
Easy Pilot function
The Easy Pilot function allows editing temporarily a route set
and followed by the autopilot, but keeping the route unchanged.
This function is useful to make corrections at
once (e.g., because of other boats or to approach
points of interests), without having to edit the
route planned or disable the autopilot.
To enable this function, rotate the knob and
position the EBL on the new route to follow,
then press ENTER. The EBL will change color,
as the boat starts following the new route; the
planned route will be abandoned, although dis-
played. To go back to the planned route, thus
canceling the temporary correction, press CLR.
NOTE: The Easy Pilot function can be enabled only if a route is present.
To enable the Autozoom function, press ZOOM+ until the
“AUTOZOOM ? ENTER = YES”message is displayed, then
confirm by pressing ENTER. To disable the Autozoom function,
press ZOOM.
When the GEONAV is turned on, and if at least one waypoint
has been previously entered, the Autozoom function will be
automatically enabled.
Screen Amplifier
This function automatically re-
draws the chart according to the
boat’s course, so as to maintain
2/3rds of the screen ahead of the
boat, provided that the boat’s
speed is greater than 3 knots.
To enable/disable the Screen
Amplifier function, press the
PAGE key to display the menu, se-
lect SETUP, the SCREEN AM-
PLIFIER option, then ON or OFF.
This function will be enabled pro-
vided that no waypoint has been
previously entered.

The EBL (Electronic
Bearing Line) and VRM
(Variable Range
Marker) functions al-
low entering markers
and waypoints as range
and bearing coordi-
nates with respect to
the current position.

by:
•Disabling the land filling function
•Adding OVZ after RANGE within the navigation window
To enable/disable the Overzoom function, press PAGE to dis-
play the menu bar, then select SETUP, OVERZOOM and ON/
OFF.
Position calibration
All position sensors are affected by intrinsic errors that make
the boat’s position incorrect (from few meters to several hun-
dred meters).
The position calibration function allows correcting manually
the position error present in all GPS, provided that this error
is not greater than 2 nautical miles.
Press PAGE to display the menu bar, select SETUP, CALIBRA-
