Introduction
The GPSMAP® 640 is both a marine and an automotive GPSenabled navigation device. When you place the device in a mount
installed on your boat, it powers on in marine mode. When
you place the device in an automotive mount, it powers on in
automotive mode.
This manual is divided in two sections. The rst section describes
how to use the GPSMAP 640 in marine mode, and the second
section describes how to use the device in automotive mode. The
sections are labeled with tabs along the edge of the page to help
identify the usage mode.

Introduction
Caring for Your GPSMAP 640
Your GPSMAP 640 contains sensitive electronic components that
can be permanently damaged if exposed to excessive shock or
vibration. To minimize the risk of damage to your GPSMAP 640,
avoid dropping your unit and operating it in high-shock and highvibration environments.
Cleaning the Unit
The GPSMAP 640 is constructed of high-quality materials and
does not require user maintenance other than cleaning. Clean
the outer casing of the unit (not the touchscreen) using a cloth
dampened with a mild detergent solution, and then wipe it dry.
Avoid chemical cleaners and solvents that can damage plastic
components.
Cleaning the Touch Screen
Clean the touchscreen with a soft, clean, lint-free cloth. Use water,
isopropyl alcohol, or eyeglass cleaner, if needed. Apply the liquid
to the cloth, and then gently wipe the touchscreen.
Protecting Your GPSMAP 640
Do not store the GPSMAP 640 where prolonged exposure to
•
extreme temperatures can occur, because it can cause permanent
damage.
Although a PDA stylus can be used to operate the touchscreen,
•
never attempt this while operating a vehicle. Never use a hard or
sharp object to operate the touchscreen because damage might
result.
Water Immersion
The unit is waterproof to IEC Standard 60529 IPX7. It can
withstand immersion in 1 meter of water for 30 minutes. Prolonged
submersion can cause damage to the unit. After submersion, be
certain to wipe and air dry the unit before reuse.
Avoiding Theft
To avoid theft, remove the unit and mount from sight when not
•
in use.
Do not keep your unit in the glove compartment.

boat. The power connector and speaker assembly are not water
resistant, and therefore unsuitable for marine use. Additionally, do
not use the automotive-mount base in your boat. The automotivemount base does not connect to the dashboard using mounting
hardware, and therefore is not stable in marine conditions.
To install the marine mounting bracket in your boat, see the
GPSMAP 620/640 Marine Mount Installation Instructions.

down on each of the four sides. The base bends and conforms
to your dashboard.
2. Snap the mounting bracket onto the automotive-mount arm.
3. Plug the vehicle power cable into a power outlet in your vehicle.
TIP: If the bottom surface of the automotive mount slides on the
dash due to dust and dirt buildup, wipe it clean using a wet cloth.
To place the GPSMAP 640 in
the mounting bracket:
1. Flip up the locking tab on top
of the mounting bracket.
2. Fit the bottom of the device
into the cradle.
3. Tilt the device back until it
stops.
4. Flip down the locking tab
to hold the device in the
mounting bracket.
To remove the GPSMAP 640 from the mounting bracket:
1. Flip up the locking tab on top of the mounting bracket.
2. Tilt the device forward, and lift it out of the mounting bracket.

(according to your heading), and provides a visual navigation aid.
When navigating, you can use the Perspective 3D screen to better
follow your course, indicated by a highlighted line. See page 14 for
more information on navigating with the GPSMAP 640.
To access the Perspective 3D screen from the Home screen, touch
Charts > Perspective 3D.
Touch the button to move the view closer to your boat and
lower to the water. Touch the button to move the view away
from the boat. This is momentarily indicated by the scale ( ) at
the bottom of the screen.

Using BlueChart g2 Vision
Optional BlueChart g2 Vision preprogrammed SD cards allow you
to get the most out of your GPSMAP 640. In addition to detailed
marine charting, BlueChart g2 Vision has the following features:
Mariner’s Eye 3D
•
the boat for a three-dimensional navigation aid. The BlueChart
g2 Vision Mariner’s Eye 3D is more detailed than the standard
Perspective 3D screen.
•
Fish Eye 3D

information on the chart.
Fishing Charts—displays the chart with enhanced bottom

contours and without navigational data. This chart works well
for offshore deep-sea shing.
•

satellite images for a realistic view of the land and water on the
Navigation chart.
•

and other points of interest (POIs) along the shore.
•

Using Mariner’s Eye 3D
When using a BlueChart g2 Vision SD card, you can view the
Mariner’s Eye 3D screen. The Mariner’s Eye 3D screen is similar
to the Perspective 3D screen (page 10), but renders a true 3D
screen. This view is helpful when navigating tricky shoals, reefs,
bridges, or channels, and is benecial when trying to identify entry
and exit routes in unfamiliar harbors or anchorages. Mariner’s Eye
3D provides a three-dimensional view of both the shore and the sea
oor.
To access the Mariner’s Eye 3D screen from the Home screen,
touch Charts > Mariner’s Eye 3D.
As with the Perspective 3D screen, touch the button to move
the view closer to your boat and lower to the water. Touch the
button to move the view away from the boat. This is momentarily
indicated by the scale ( ) at the bottom of the screen.
Touch and drag the map to the left or the right to pan the 3D
perspective.

Marine Mode: Using Charts
Using Fish Eye 3D
Using the depth contour lines of the BlueChart g2 Vision
cartography, Fish Eye 3D provides an underwater view of the sea
oor or lake bottom. The and buttons adjust the view in the
same way as the Mariner’s Eye 3D.
To access the Fish Eye 3D screen from the Home screen, touch
Charts > Fish Eye 3D.
NOTE:
When navigating, the magenta line will not appear on the
Fish Eye 3D screen, though any enabled navigation data bars will
appear.
Using Fishing Charts
Use the shing chart to view detailed bottom contours and depth
soundings on the chart. There are no navigation aids such as buoys
and lights on the shing chart.
The shing chart uses highly detailed bathymetric data contained
on a preprogrammed BlueChart g2 Vision SD card, and is best for
offshore deep-sea shing.

Enabling High�ResolutionHigh�Resolution Satellite
Imagery
You can overlay high-resolution satellite images on the land,
the sea, or both portions of the Navigation chart when using a
preprogrammed BlueChart g2 Vision SD card.
