INTRODUCTION
The GEONAV is a chart plotter that displays your boat’s cur-
rent position with respect to an electronic chart.
The unit can be optionally equipped with a built-in GPS re-
ceiver that can track up to 12 satellites simultaneously and be
interfaced with:
• An external GPS
• A depth sounder
• An autopilot
By using a GEONAV and a NAVIONICS electronic chart, you will
never get lost even in bad weather conditions such as fog, rain or
dark because your plotter will always display where you are and
where your are heading to.
The ROUTE function will allow you to plan a trip, MARKERS will
allow you to mark points of interest whereas the TRACK function
will allow you to record your actual route. Thanks to the un-
limited capacity of the new CompactFlash™ cartridges - that
can also be used on PCs as personal hard disks - the instru-
ment can store a large amount of route, track and marker data.
NAVIONICS GOLD CHARTS are available for all the most popu-
lar boating areas and can be used in addition to official paper
charts to obtain additional information, such as the availabil-
ity of port services, as well as tides and currents data.
NAVIONICS electronic charts are available worldwide 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.

EnglishEnglish
•Autopilot: To connect the GEONAV to an autopilot, use the
data cable provided with the unit (see the Connections Sec-
tion).
•Depth sounder: To connect the GEONAV to a depth sounder, use
the data cable provided with the unit (see the Connections Sec-
tion).
Fixed mounting
The plotter can be mounted
on any surface using the
mounting bracket provided
with the unit (see figure).
Use 4 flat-head screws (5mm)
to fix the bracket to the de-
sired mounting surface.
Since the bracket does not
allow any left or right rota-
tion, make sure that the unit
is properly installed for the
best view angle.
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 re-
duce 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
To avoid electromagnetic interference, the GEONAV must be
positioned at least 0.35 meters away from magnetic compasses
or flux-gate sensors, such as those used on autopilots and
remote electronic compasses.
The GEONAV is water resistant, but not waterproof. It is es-
sential that the rubber cover on the right side of the unit is
firmly inserted into the cartridge slot; the rubber cover should
be removed only when the CompactFlash™ has to be inserted
or replaced and, in this case, the unit must be perfectly dry.
NOTE: Any damage caused by the presence of water inside the cartridge slot, due
to the cover missing or incorrectly replaced, is specifically excluded from the war-
ranty.
Cleaning
It is recommended that you use a non-alcoholic product to clean
the glass, since alcoholic products may damage the glass surface
or make it opaque.
Installation
The GEONAV allows using either the built-in antenna for outdoor
installation or an external GPS antenna for indoor use.
NOTE: At start-up, the plotter will select the internal GPS by default.
•Internal GPS (if available):For the best reception of satellites,
mount your unit in an open area to allow the built-in an-
tenna to have the best sky visibility. If the instrument is
installed so as to allow full horizon visibility, the best per-
formance will be ensured.
•External GPS:Instead of a built-in antenna, you can use an
external GPS. To connect the GEONAV to an external an-
tenna, use the data cable provided with the unit (see the
Connections Section).

Cartridge Installation
WARNING: The rubber cover should be removed only when inserting or replacing
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.

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.
Internal or external GPS
To make the installation easy, the GEONAV can use either its
own internal GPS receiver (if available) or an external receiver,
depending on where the unit is to be installed (indoor or out-
door).
To select the internal/external GPS, press PAGE to display the menu,
select SETUP, then GPS INT or GPS EXT.
Depth sounder
When in depth sounder mode, the GEONAV displays the naviga-
tion window in the screen upper part, and, in the bottom part, the
sea depth in graphic form.
The depth value can be expressed in meters (selected by default),
feet and fathoms; press PAGE to display the menu, select SETUP
and then DEPTH UNITS (M/FT/FA).
Navigation mode (Automatic)
The GEONAV enters the Navigation mode as soon as the internal
or external GPS receiver 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 selects the chart scale and updates the boat’s position on
the screen.

Functional Characteristics
cally the boat’s position and the target waypoint at the best
available chart range. As the boat
approaches the target waypoint,
the unit will automatically zoom
in. Once the waypoint is passed,
the unit will select the best range
to display the boat’s position and
the following waypoint.
To activate the Autozoom function, press ZOOM+ until the
“AUTOZOOM ? ENTER = YES” message is displayed.
To deactivate the Autozoom function, press the ZOOM key once.
When the GEONAV is turned on, and if at least one waypoint
has been previously entered, the Autozoom function is auto-
matically activated.
Screen Amplifier
This function automatically redraws the chart according to
the boat’s course, to maintain 2/3rds of the screen ahead of
the boat, provided that the boat’s
speed is greater than 3 knots.
This function will be activated
only if no waypoint has been
previously inserted.
Overzoom
The Overzoom function allows
the chart scale to expand any-
where up to 1/4 NM. The
Overzoom does not provide any
additional chart detail, but im-
proves only the readability of the
existing information, thus act-
ing as a magnifying glass.
When the Overzoom is activated,
the unit will warn the user by
Cursor mode (Manual)
When in Cursor mode, the manual cursor is displayed. It is
possible to edit a route, insert or delete markers, display navaid
information etc., but it is not possible to gain access to the
depth sounder window. By pressing one of the four arrows in
the CURSOR key, the unit switches from Navigation to Cursor
mode, and the screen is centered in relation to the manual
cursor. To return to Navigation mode press PAGE.
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 ro-
tating the electronic chart displayed ac-
cording to the plotted route (COG -
Course Over Ground) as detected by the
GPS receiver. Since the COG value var-
ies continuously, a filter has been in-
serted to prevent the chart from bounc-
ing.
To activate 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 requested maximum range be-
fore activating the chart rotation.
The northern direction will be indi-
cated by the symbol .

replacing RANGE with OVZ (blinking) within the navigation
window.
To activate/deactivate the Overzoom function, press PAGE un-
til the menu bar is displayed, then select SETUP, OVERZOOM
and ON/OFF.
Position calibration
Most position sensors have intrinsic errors that make the boat’s
position incorrect (from few meters to several hundred meters)
with respect to the background display of the chart.
This error is caused by the principle at the root of the satel-
lite-derived position system.
The position calibration allows the user to manually correct
the position error present in all GPS. Press PAGE until the
menu bar is displayed, select SETUP, CALIBRATION and then
ON.
A message will prompt the user to move the cursor to the boat’s
true position by using the CURSOR key. Press ENTER to move
the GPS boat’s position to the point indicated by the cursor.
This operation will save the calibration for use in future cal-
culations.
NOTE: When the calibration is activated, the coordinates will be marked by (*).
To cancel calibration, press PAGE until the menu bar is dis-
played, select SETUP, CALIBRATION and then OFF.
Local time
By this function the user can enter local time instead of the
Greenwich time (GMT) supplied by the GPS receiver.
To enter local time, press PAGE until the menu bar is dis-
played, select SETUP, SET TIME and then LOCAL.
A window will allow entering local time by using the CURSOR
key. Press ENTER to confirm the operation.

Satellite Window
SATELLITE WINDOW
NOTE: If a NAVIONICS cartridge with the Tides and Currents feature has been
inserted, the Satellite window will disappear as soon as a valid fix is obtained and be
replaced by the Info window.
At start-up the satellite window
displays how many and which
satellites are tracked by the GPS
receiver.
The outer circle represents the
horizon, the inner one identifies
a 45° elevation with respect to
the horizon, and the central
circle points to the zenith.
The small squares with numbers
show the satellites available.
As soon as a satellite is tracked
by the GPS receiver, the square
turns red. The bars displayed on
the left identify the signal qual-
ity; the longer the bar, the higher
the signal quality.
On the left of each bar, two digits indicate numerically the
signal/noise ratio.
Additional information:
•Day, month, year, local or Greenwich time (at the first
start-up the GEONAV is initialized to Greenwich Time).
•Boat’s position (lat/lon) (or the latest valid fix if the GPS
receiver is still searching for satellites).
•Data on the current satellite situation (number and fix).
•SOG, COG and altitude.
Operating Modes
OPERATING MODES
The GEONAV can operate in two different modes, Cursor and
Navigation, each giving access to different functions.

tronic chart, as well as editing or creating the route. See the
Route Section for more details.
To enter the Cursor mode, press the CURSOR key.
NAVIGATION MODE
In Navigation mode, the boat’s position icon replaces the
crosshair cursor and several data windows can be accessed.
To enter the Navigation mode, press the PAGE key repeatedly.
As the fix is valid, the windows sequence is the following:
SATELLITE > NAVIGATION > MENU > DEPTH SOUNDER > TRIP >
INFO
The Depth Sounder window is displayed provided that data
is received from a depth sounder.

NAVIGATION WINDOW
This window is activated automatically as soon as the GPS
receiver has obtained the boat’s position (FIX OK).
If no route is present, speed, course and chart range are dis-
played at the bottom of the screen.
By using the ZOOM key, the chart detail level can be increased,
thus accessing NAVIONICS chart data.
If a route has been inserted, the screen will display the fol-
lowing data:
• Boat’s speed
• Distance from the target
waypoint
• Time to arrive to the target
waypoint
• Chart range
Navigation Window
The latitude and longitude values relevant to the boat’s posi-
tion are displayed as soon as three satellites are tracked and a
2D fix (two dimensions) is available.
The altitude value is available only if four satellites are tracked
and a 3D fix is obtained.
As soon as a valid fix is available, the GEONAV will automati-
cally switch to Navigation mode and display the boat’s posi-
tion at the best chart range available; the window at the bot-
tom of the screen will indicate the boat’s course and speed.

DEPTH SOUNDER WINDOW
A depth sensor can be interfaced with the GEONAV via NMEA.
In this case, the GEONAV auto-
matically enables the depth
sounder function, displaying a
graph of sea depth.
The depth scale, whose unit can
be selected from the menu in
meters, feet or fathoms, will
change automatically to show
deeper or shallower water.
In Navigation mode, press PAGE
until the depth sounder window
appears.
The window will display the fol-
lowing data:
• Water depth
• Depth scale
• Water temperature (if available)
When navigating in waters deeper than sounder access range or if
the boat’s speed is too high for depth sounding, data acquisition
will be interrupted and the number replaced by “—”.
To deactivate the depth sounder window, press PAGE.
Depth Sounder Window

Trip Window
Info Window
INFO WINDOW
When a NAVIONICS cartridge featuring Tides and Currents
data is present, this window displays further information,
besides the forecast data supplied by selecting the Tides and
Currents station.
The following data is displayed:
•Latitude and longitude at the
current boat’s position
•Current time and date
•Value of magnetic variation
received by the GPS
•Dawn and sunset time
•Moonrise and moonset time
•Moon phase
•Graph of estimated tide level
with respect to the current
position
WARNING: Unlike the graph displayed at a T&C station position (accessible through
the GOTO function, or by positioning the cursor on the Tides and Currents station
symbol) which is as accurate as supplied by hydrographic offices, this graph shows
estimated data, being the result of interpolation between the two Tides and Currents
stations nearest to the point of interest. The accuracy of the estimate may vary,
depending on the coast type, the distance to the nearest stations, and other geo-
graphical features.
