INTRODUCTION
The GEONAV 4C is a handheld chartplotter that displays your
boat’s current position with respect to an electronic chart.
The unit is equipped with a built-in GPS receiver that can
track up to 12 satellites simultaneously and be interfaced with:
• An external GPS
• A depth sounder
• An autopilot
The unit can be installed onboard, interfaced with the NMEA
instruments and - at the same time - work as a portable instrument, thanks to four AA alkaline cells or rechargeable batteries.
The unit is also equipped with a built-in battery charger that
starts operating automatically when the unit is powered. Totally waterproof (IPX7), the unit is equipped with a daylight
visible, color TFT display.
By using a GEONAV 4C and a NAVIONICS Gold electronic
chart, you will never get lost even at night, and in case of bad
weather or reduced visibility because your plotter will always
display where you are and where your are heading for.
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 unlimited capacity of the new CompactFlash™ cartridges that can also be used on PCs as personal hard disks - the
instrument can store a large amount of route, track and marker
data.
charts to obtain additional information, such as the availability of port services, as well as tides and currents data.

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 totally waterproof (IPX7) and weatherproof. It
is essential that the battery pack on the unit’s rear side is
firmly inserted and tightly screwed and that the battery pack
is removed only when the CompactFlash™ or batteries need
replacing. Always make sure that, during the replacement operations, the unit is perfectly dry.
NOTE: Any damage caused by the presence of water inside the unit, due to the lack
or incorrect installation of the battery pack, is specifically excluded from the warranty.
Cleaning
It is recommended that you use a nonalcoholic 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: For the best reception of satellites, mount your
unit in an open area to allow the built-in antenna to have
the best sky visibility. If the instrument is installed so as
to allow full horizon visibility, the best performance will
be ensured.
• External GPS: Instead of a built-in antenna, you can use an
external GPS. To connect the GEONAV to an external antenna, use the optional NMEA data cable (see the Connec-
tions Section).

• Autopilot: To connect the GEONAV to an autopilot, use the
optional NMEA data cable (see the Connections Section).
• Depth sounder: To connect the GEONAV to a depth sounder,
use the optional NMEA data cable (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 countersunk head screws (4mm) to fix the bracket to
the desired mounting surface. Since the bracket does not allow any left or right rotation, make sure that the unit is properly installed for the best view angle.
CONNECTIONS
Power supply
The GEONAV can be powered by using the appropriate power supply
cable with car lighter plug or the
built-in battery pack.
Install the power supply cable with
the connector in the position shown
in the figure, then exert a light pressure until clicking.
To remove the cable, extract the ring
nut without rotating it.
When the cable is disconnected, make
sure that the connector is protected
by the appropriate rubber cap.
External power supply
The car lighter adapter has a little
lamp (LED) that goes on if the car is correctly providing power to the bracket.
If the lamp is off:
• check that the 12V voltage is available
from the lighter plug;
• open the adapter and check the fuse.
If the fuse is broken, replace it with a fuse
having the same electrical characteristics.
DO NOT USE ANY BYPASS CIRCUIT.

Battery pack
The battery pack of the GEONAV allows
you to use it as a portable unit. Use 4
alkaline cells or rechargeable batteries,
AA size (if possible, high-capacity batteries, 2000mAh or higher).
Make sure that the unit is off and dry
when replacing the batteries.
To access the battery slot, loosen the locking screws by means of a coin or the round
side of a key, as shown in the figure.
Extract the battery pack, flip it over and
loosen the cover locking screws.
Remove the cover and insert the batteries according to the polarity indicated.
Make sure that the “Battery type” selector located in the cartridge slot is positioned correctly, according to the type
of battery used (“Rechargeable” position,
for rechargeable batteries; “Alkaline” position, for alkaline batteries).
To change the selection, move the small
lever by means of a sharp object.
WARNING: All the units are supplied with the battery
selector set to “Alkaline”. When using alkaline batteries, the selector has to be set to “Alkaline”. You are
warned NEVER to use alkaline-type batteries if the
selector is set to “Rechargeable”. In this case the unit
can be seriously damaged. This kind of damage is not
covered by the warranty. When using rechargeable
batteries, the selector can be set either to
“Rechargeable” or to “Alkaline”. However
the battery charge function is active on condition that the selector is set to “Rechargeable”. The misplacement of the selector may
cause the batteries to break, the corrosive
liquid to leak out and, consequently, the unit
to be damaged. This kind of damage is not
covered by the warranty.
Check that the contacts in the battery
pack are clean and dry.
Before reassembling the battery pack,
make sure that the rubber gasket in the
slot and the rubber O-rings tightening
the locking screws are clean and in the
correct position.
The misplacement of the gaskets, together with any presence
of sand, saline residues or dirt, may be detrimental to the
tightness of the battery slot since it allows moisture to penetrate into the unit and damage the electronic inner components. This kind of damage is not covered by the warranty.
Reassemble the battery pack carrying out the disassembly operations in reverse order.
Should the battery pack not fit, or fit with difficulty in its
seat, check that the CompactFlash™ is correctly inserted.
The partial extraction of the CompactFlash™ blocks the insertion of the battery pack.
The unit can be powered by the batteries only or connected to
an external power supply. When the unit is powered by the
power supply cable, the inner batteries - if they are of rechargeable type - are fully recharged, after which the inner
battery charger is automatically disabled and the batteries disconnected in order to keep their charge.

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 1 second.
Internal or external GPS
To make the installation easy, the GEONAV can use either its
own internal GPS receiver or an external receiver, depending
on where the unit is to be installed (indoor or outdoor).
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 navigation 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 automatically selects the chart scale and updates the boat’s position on
the screen.
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 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.
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 before activating the chart rotation.

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 automatically 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 anywhere up to 1/4 NM. The
Overzoom does not provide any
additional chart detail, but improves only the readability of the
existing information, thus acting as a magnifying glass.
When the Overzoom is activated,
the unit will warn the user by
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.
Without screen amplifier
With screen amplifier
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 satellite-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 calculations.
NOTE: When the calibration is activated, the coordinates will be marked by (*).

OPERATING MODES
The GEONAV can operate in two different modes, Cursor and
Navigation, each giving access to different functions.
CURSOR MODE
When the GEONAV is in Cursor mode, the crosshair cursor is
displayed. The CURSOR key allow browsing through the electronic 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 >
LAT/LON > INFO > RUNWAY
The Depth Sounder window is displayed provided that data
is received from a depth sounder.
The Info window is displayed provided that a NAVIONICS
cartridge featuring Tides and Currents data is active (see the
Info Window Section).
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. The
numbers of differential satellites,
if any, are displayed from bottom to top.
As soon as the satellite is tracked by the GPS receiver, the
square turns red. The bars displayed on the left identify the
signal quality; 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.
The latitude and longitude values relevant to the boat’s position 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 automatically switch to Navigation mode and display the boat’s position at the best chart range available; the window at the bottom of the screen will indicate the boat’s course and speed.
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 displayed 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
