INTRODUCTION
The GEONAV is a chart plotter that displays your boat’s current position with respect to an electronic chart.
The unit can be optionally 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
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 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.
NAVIONICS GOLD 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 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.

Installation and Precautions

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 essential 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 warranty.
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 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 data cable provided with the unit (see the
Connections Section).
•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 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.
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.

The GEONAV will add the following messages: APA - APB XTE - RMB - BWC - GLL - VTG
The data cable is supplied together with the GEONAV plotter.
WARNING: Once the installation is completed, always make sure that all wires are
properly connected since wrong connections may damage the unit.
CARTRIDGE INSTALLATION
Installing the CompactFlash™
Remove the rubber cap from the cartridge slot located in the
right-hand side of the plotter.
Insert the cartridge into the appropriate slot, with the label
side (side with a small arrow) backwards and push it.
Replace the cap exercising firm 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.
Removing the CompactFlash™
Make sure that the plotter is perfectly dry.
Remove the rubber cap from the cartridge slot located in the
right-hand side of the plotter, then extract the cartridge.

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.

DIAGNOSTIC
The GEONAV features a diagnostic program to verify its correct performance, once installed, and to detect problems that
may occur during the use of the unit.
To access the diagnostic program, keep pressed any key but
CLR, while pressing the PWR key.
The GEONAV will switch on and carry out automatically a
test of the whole system; as soon as the memory test is completed, the program will test the LCD, the CompactFlash™
card and the keyboard. Press ENTER to run one test, CLR to skip
to the next one. To exit from the keyboard test, press CLR
twice.
Once the keyboard test is completed, the diagnostic program
allows checking the messages received from the GPS through
the NMEA 0183 port. Hold the ENTER key pressed to freeze the
messages on the screen, then release it to keep on displaying
the new messages sent by the GPS. To test channel 2 (depth
sounder or wind instrument), press GOTO. Press CLR to quit.
After the keyboard, the diagnostic program will test the internal GPS (if available) and the backlight. Press ENTER to run
one test, CLR to skip to the next one.
Once terminated all tests, press ENTER to re-boot the unit.
WARNING: The internal memory can be cleared by pressing simultaneously the
PWR and CLR keys. This operation will delete all the settings stored in the GEONAV
and restore factory settings.
NOTE: In case of damaged cartridge or abnormal power spikes, the unit might lock,
requiring a power shutdown to restart. In that case, the unit can be turned off without
the need of detaching the power, by simply pressing the GOTO, PAGE and CLEAR
keys at the same time. This function is useful if the unit is panel mounted or flush
mounted and the power switch cannot be easily accessed.
NAVIONICS ELECTRONIC CHARTS
The GEONAV includes a built-in world map that allows zooming from 4,096 down to 512NM. Additional cartography details relative to a specific area of navigation are available from
the CompactFlash™ cartridges storing NAVIONICS GOLD
CHARTS.
To display chart boundaries, press PAGE until the menu bar
appears, select SETUP, CHART BOUNDARIES, then select
ON/OFF to enable/disable the boundaries of the charts stored
in the cartridge. A small square will locate the area covered by
the cartridge installed.
Increasing/decreasing the chart range
Press the -ZOOM+ key.
Displaying depth and safety contours,
geographical names, spot soundings
and light sectors
Press PAGE to display the menu,
select SETUP and enable the
option desired (Depth Cont.,
Safety Cont., Spot Soundings,
Names or Light Sectors) by using the CURSOR key.
Converting depth values into the units
set
Press PAGE to display the menu,
select SETUP, DEPTH UNITS
and then set the unit desired to
meters, feet or fathoms.
The GEONAV will convert all the depth values in the unit
selected, making them appear like those reported in the official nautical charts (see the figure).
