INTRODUCTION

The GEONAV is a graphic GPS plotter that displays your boat’s current

position with respect to an electronic chart.

The Plus model is equipped with a built-in GPS receiver.

The Elite and Regatta models are equipped with built-in GPS receivers with

external differential inputs.

The Cabin model must be connected to an external GPS receiver.

The GEONAV can track up to 12 satellites simultaneously and can be

interfaced with:

• A DGPS antenna when using the built-in GPS

• An external GPS

• A depth sounder

• An autopilot

• A mast head transducer

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 be-

cause 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.

NAVIONICS chart cartridges are available for all popular boating areas

around the world and can be used in addition to your official paper

charts. NAVIONICS chart cartridges are available from authorized

NAVIONICS dealers and outlets around the world.

See your local marine electronics dealer for further information.

Introduction

The GEONAV unit is equipped with accessories for installation in your

boat and car.

The GEONAV can also be used for land applications; the GPS receiver

and the new NAVIONICS land charts will allow displaying easily your

position with respect to the most popular roads and city names.

The installation of the GEONAV in your car will take you only a few

seconds; position the plotter on the dashboard with the suitable bracket,

fix the suction cup to the front window, connect the power cable to the

lighter and press the ON key.

Enjoy your trip.

• 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 section).

• Depth sounder: To connect the GEONAV to a depth sounder, use the

data cable provided with the unit (see the Connections section).

• Mast head transducer: To connect the GEONAV to a mast head trans-

ducer, use the data cable provided with the unit (see the Connections

section).

NOTE: Since only one NMEA 0183 input is available in addition to the input used for connect-

ing to the GPS, the depth sounder must be connected through an NMEA 0183 mixer or a

bridge to instrument networks.

Fixed installation (on boat)

The plotter can be mounted on any sur-

face using the mounting bracket pro-

vided with the unit (see figure).

Use the 3 flat-head screws (6mm) to fix

the bracket to the desired mounting sur-

face. Since the bracket does not allow

any left or right rotation, make sure that

the unit is properly installed for the best

view angle.

In the event that you wish to connect

the power cable directly to the boat bat-

tery, cut the car lighter adapter off; we

recommend the installation of a 1A fuse

between the power source and the plot-

ter to protect the instrument against ov-

ervoltage and/or overcurrent.

When the plotter is taken away from the

bracket, we recommend that you use

the bracket cap supplied with the

GEONAV to protect the electrical con-

tacts against water.

INSTALLATION AND PRECAUTIONS

SAFE DISTANCES: When installed on a boat, in order to avoid electro-

magnetic interference, the GEONAV must be positioned at least 0.15

meters away from magnetic compasses or a flux-gate sensors, such as

those used on autopilots and remote electronic compasses.

ENVIRONMENT: 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 Navchart™ has to be inserted or replaced and, in this case, the

unit must be perfectly dry.

NOTE: Any damage caused by water into the cartridge slot 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 instal-

lation 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.

When using the built-in GPS receiver, the GEONAV can be interfaced

with a DGPS (RTCM).

ATTENTION: The GEONAV can be connected to several DGPS whose function modes are

the following:

a) automatic frequency selection, or

b) manual frequency selection with a wave-change switch.

• DGPS: To connect the GEONAV to a DGPS antenna, use the data cable

provided with the unit (see the Connections section).

This step is very important to ensure safe operation while driving.

Test the connection between the unit and the window several times

after installation and during use when you start up the car and on

other occasions.

7. Place the mounting bracket on top of the dashboard and position the

plotter so as to ensure the best visibility of the screen and for the

internal GPS antenna.

8. Plug the power cord into the lighter adapter.

NOTE: Some cars disable the power supply, for example when they are switched on. In this case,

the GEONAV will go out as well.

Panel mounting

Locate the area where the GEONAV is to be installed, then make the

holes in the panel using the appropriate drilling template supplied.

Apply the neoprene adhesive gasket to the rear of the plotter to reduce

moisture penetration and vibrations.

Position and fix the unit to the panel by 4 screws 4 mm in diameter and

maximum 5 mm in length, plus panel thickness.

Do not tighten the screws too firmly, in order not to damage the screw

seats.

Car installation

To allow an easy installation on your car,

the GEONAV is supplied with an addi-

tional bracket equipped with a suction

cup. When the unit is installed, make

sure that your car front window has

enough space to allow good road vis-

ibility.

The installation procedure is the follow-

ing:

1. Locate a flat surface on the window

that allows you to position the

bracket base on the dashboard as

well as the internal GPS to have the

best sky visibility (the GPS has to

track satellites and therefore to see

the sky).

2. Clean the entire front window area

suitable for installing the unit. Use

a good window cleaner and paper

towels and dry the area completely.

3. Verify that the GEONAV does not in-

terfere with levers, airbags and other

car facilities.

4. Pull the suction cup lever back.

5. Place the suction cup firmly on the

clean, flat glass surface and push the

lever forward to make it adhere to

the glass.

6. Make sure that the unit is firmly se-

cured and correctly positioned and

that will not come off the window.

Fixed installation

The plotter can be mounted on any surface using the mounting bracket

provided with the unit (see figure). Use the 4 flat-head screws (6mm) 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.

We recommend the installation of a 1A fuse between the power source

and the plotter to protect the instrument against overvoltage and/or

overcurrent.

DIAGNOSTIC

The GEONAV has a diagnostic program to verify its correct performance

once installed and to detect problems that may occur during the unit

operation. To perform these tests, switch the unit on by pressing simul-

taneously ON and another key (except for CLR).

The GEONAV will automatically perform a test of the entire system; as

soon as the memory test is completed, the program allows verifying

whether each key works properly. An outline of the keyboard is dis-

played; press each key and check whether the corresponding key on the

screen turns black. If the key is faulty, no change in color will occur.

The diagnostic program allows checking the correct connection between

the built-in antenna or an external GPS and the unit (channel 0). The

position sensor should be operating and should transmit NMEA 0183

messages. If the receiver is working, you will see a string of NMEA 0183

messages being displayed to indicate that the whole system is working

correctly.

Keep CLR pressed to freeze the messages on the screen, then release CLR

to keep on displaying NMEA 0183 messages.

To test channel 1 (depth sounder), press ZOOM-, to go back testing chan-

nel 0, press ZOOM+.

Press ENTER to exit the diagnostic program.

ATTENTION: It is possible to clear the contents of the GEONAV internal memory (not the

Navchart™) and to reset the plotter to the starting point. To perform a memory reset, switch the

unit on by pressing simultaneously the ON and CLR keys.

FUNCTIONAL CHARACTERISTICS

This chapter summarizes the most commonly used functions of the

GEONAV and gives also a brief description of the terms that will appear

in the following pages. Additional terms and acronyms can be found in

the Glossary section at the end of this manual.

Internal or external GPS

To make the installation easy, the GEONAV can use either its own inter-

nal 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. The selection of GPS INT will

open a new window; select “YES” if the plotter is connected to a DGPS

compatible with the internal GPS, otherwise select “NO”. Confirm the

operation by pressing ENTER.

Depth sounder

When in depth sounder mode, the GEONAV displays the navigation win-

dow 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, AUTO)

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 se-

lects the chart scale and updates the boat’s position on the screen.

Cursor mode (Manual, MAN)

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 Cursor to Navigation mode, and the screen is centered in relation

to the manual cursor.

To return to Navigation mode press PAGE.

Functional Characteristics

The services available depend on the NAVIONICS cartridge used.

NAVIGATIONAL AIDS

Displaying port services

The symbol identifies a port providing ser-

vices. Zoom down to 1 NM, position the

manual cursor on the icon (sailing boat)

relevant to the selected marina; press EN-

TER and a window will list all the services

available in that port. Select the desired

2726

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, acting as a magnifying

glass.

When the Overzoom is activated, the unit will

warn the user by:

• deactivating the land filling function;

• replacing RANGE with OVZ (blinking) within

the navigation window.

To activate/deactivate the Overzoom function, press PAGE until 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 posi-

tion 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 (*) for safety pur-

poses.

To cancel calibration, press PAGE until the menu bar is displayed, select

SETUP, CALIBRATION and then OFF.

Functional Characteristics

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.

This function will be activated only if no waypoint has been previously

inserted.

Chart rotation

Charts are traditionally displayed in north-up

mode. This, however, does not correspond to

reality. For example, when traveling south-

wards, 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 plot-

ted route (COG - Course Over Ground) as de-

tected 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 maxi-

mum range before activating the chart rota-

tion.

Autozoom

With the Autozoom function the GEONAV will

always display automatically the boat’s posi-

tion and the target waypoint at the best avail-

able chart range.

OPERATION

At start-up the GEONAV displays a message warning the user that the

electronic chart is a navigation aid designed to facilitate the use of au-

thorized government charts, not to replace them.

Adjust the contrast by pressing CURSOR or activate the backlight by press-

ing ON. Press PAGE to continue; the GEONAV will display the GPS infor-

mation window.

The GEONAV is able to display five graphic windows: to switch from one

window to another, press PAGE.

When the fix is valid, the window sequence is the following:

SATELLITES > NAVIGATION > MENU > NAVIG. TO WP > TRIP

SATELLITES > NAVIGATION > MENU > DEPTH SOUNDER > TRIP

By pressing CURSOR the GEONAV switches

to Cursor mode, allowing the user to move

freely within the seamless world of

NAVIONICS charts. The screen will always

be centered with respect to the manual

cursor; the window at the bottom of the

screen displays the following data:

• Distance from the boat’s position to the

manual cursor

• Time to arrive to the manual cursor po-

sition (estimated with respect to the

current boat’s speed)

• Bearing from the boat’s position to the

manual cursor

• Chart range

Operation

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 displayed, select

SETUP, REFER. TIME and then LOCAL. A window will allow entering

local time by using the CURSOR key. Press ENTER to confirm the operation.

To cancel local time, press PAGE until the menu bar is displayed, select

SETUP, REFER. TIME and then GMT.

The GEONAV is equipped with a 4-color screen that offers perfect visibil-

ity under sunlight. Green, white, blue and red are the colors available

and cannot be modified.

• Earth .......................................................................................red

• Sea .......................................................................................white

• Menu, windows, navaids, boat’s position ................................blue

• Tracks, waypoints ................................................................green

Contrast

Press PAGE until the menu bar is displayed and adjust the contrast with

the CURSOR key.

The contrast can be adjusted at start-up, when the WARNING message

appears or when the satellite window is displayed; press the CURSOR key

and adjust the contrast.

Since the GPS receiver is initialized in Italy, the time to get the first fix

will depend on the areas you want to navigate in; within the Mediterra-

nean Sea the GEONAV should get the first fix in less than 12 minutes,

whereas in other parts of the world it can take up to 30 minutes.

Once the unit gets the first fix, the time for the following fixes is a few

minutes.

If the boat is in an area covered by a differential station, when the built-

in antenna is used together with a DGPS, the top of the screen will

display the “FIX 3D-DIFF” or “FIX 2D-DIFF” message.

SATELLITE 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 number inside

the square is displayed in reverse. 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 quality

relevant to that satellite.

A value greater than 40 indicates a good signal quality.

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 is still search-

ing for satellites).

• Data on current satellite situation (number and fix).

• SOG, COG and altitude.

The latitude and longitude values relevant to the boat’s position are dis-

played as soon as three satellites are tracked and a 2D fix (two dimen-

sions) 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 auto-

matically 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, speed and chart range.

Menu

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 screen will

display the following data:

• Boat’s speed

• Distance from the target waypoint

• Time to arrive to the target waypoint

• Chart range

If no route is present, the boat’s speed and direction, as well as the chart

range, are displayed at the top of the screen. The window in the lower

left part of the screen displays the speed of true wind. If a route has been

inserted, the window at the top of the screen displays the following data:

• Boat’s speed

• Distance to the target waypoint

• Bearing to the target waypoint

• Time to arrive to the target waypoint

If two or more waypoints have been inserted, besides the target waypoint,

a window in the lower right corner displays apparent wind data on the

next leg. The speed of apparent wind is displayed numerically, whereas

the wind direction is shown graphically by an arrow. If a close-hauled or

a run is planned in the next leg, the arrow indicates the apparent wind

on the first beat of the next leg, whereas a single line indicates the direc-

tion of apparent wind on the waypoint. Moreover, at the boat’s position,

the following graphic data is displayed:

• Direction of true wind (magnetic), indicated by an arrow showing the

direction towards which the wind blows;

• Layline: Displayed as a line, represents the direction the ship will be

able to keep in case of tacking. The layline is displayed if the angle

between the wind direction and the ship’s allows a close-hauled or a

run; it is updated automatically as the wind changes.

When the navigation to waypoint window

is activated, the active route leg is tem-

porarily deleted and replaced with a line

constantly connecting the boat’s position

to the current target waypoint. The win-

dow at the bottom of the screen displays

the following data:

• Boat’s speed

• Distance from the boat’s position to

the target waypoint

• Bearing from the boat’s position to the

target waypoint

• Steering angle

DEPTH SOUNDER WINDOW

A depth sensor can be interfaced with the

GEONAV via NMEA.

In this case, the GEONAV automatically en-

ables the depth sounder function, display-

ing 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 ap-

pears.

The window will display the following data:

• Sea depth

• Depth scale

• Sea temperature (if available)
