How GPS and Cartography Work
Your 700 Series™ Chartplotter supports GPS and chartplotting, and uses GPS
to determine your position and display it on a grid. The Global Positioning
System (GPS) is a satellite navigation system designed and maintained by the
U.S. Department of Defense. GPS was originally intended for military use;
however, civilians may also take advantage of its highly accurate position
capabilities, typically within +/- 10 meters, depending on conditions. This
means that 95% of the time, the GPS receiver will read a location within 10
meters of your actual position. Your GPS Receiver also uses information from
WAAS (the Wide Area Augmentation System), EGNOS (the European
Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite
Augmentation System) satellites if they are available in your area.
GPS uses a constellation of 24 satellites that
continually send radio signals to the earth. Your
present position is determined by receiving signals
from up to 16 satellites and measuring the
distance from the satellites.
All satellites broadcast a uniquely coded signal
once per second at exactly the same time. The GPS
receiver on your boat receives signals from
satellites that are visible to it. Based on time
differences between each received signal, the GPS
receiver determines its distance to each satellite.
With distances known, the GPS receiver
mathematically triangulates its own position.
With once per second updates, the GPS receiver
then calculates its velocity and bearing.

The following GPS functionality is currently supported by the 700 Series™
Chartplotter when it is connected to the included GPS receiver:
• View current position
• View current track (breadcrumb trail)
• View precision speed and heading from your GPS receiver
• Save tracks, waypoints and routes
• Travel a route and navigate from one waypoint to the next.
Your 700 Series™ supports Navionics® Gold, HotMaps™ and HotMaps™ Premium
on MMC or SD card media.
NOTE: Your 700 Series™ does not support Navionics® Classic Charts, only Navionics® Gold,
HotMaps™, and HotMaps™ Premium.
Your unit also comes with a built-in UniMap™ with a more detailed map of
North America (Domestic models) or a more detailed map of Europe and
Southeast Asia, including Australia and New Zealand (International models).
Your 700 Series™ uses the GPS Receiver to determine the position of the boat
automatically, and uses the zoom level settings on a particular view to select
the best chart to display. See Viewing Cartography for more information.

3
Multi-Media Card
(MMC)/SD Slot
Your 700 Series™ Chartplotter also has a multi-
media card (MMC)/SD slot that is used to insert
optional-purchase cards containing additional
detailed maps. If you insert an MMC/SD that
contains a more detailed chart for a particular
location, your 700 Series™ Chartplotter will
retrieve that chart and display it automatically.
Use the illustration to locate the position of the MMC/SD slot cover, remove the
MMC/SD slot cover, then insert the MMC/SD into the slot. The label on the
MMC/SD should face toward the right side of the unit. Press down on the card
until it clicks into place, then replace the slot cover, making certain that the
gasket is present and positioned correctly before re-installing the cover, then
replace and tighten snugly - do NOT overtighten, as this will not improve water
resistance, and may damage the cover.
Software Updates
Use the MMC/SD slot to update the software version of your control head. To
update the software in your control head, plug in the appropriate MMC/SD card
that contains a software update file; the unit will recognize it, will tell you what
software version your control head is currently running, and will ask you if you
want to update the software in the unit to match that on the MMC/SD card.
You can obtain software updates from the www.humminbird.com website.

What’s On the Display
The 700 Series™ Chartplotter can display a variety of useful information.
Cursor Info Box: indicates the Latitude and Longitude of
the cursor position, the distance to travel to the cursor
position and the bearing to the cursor position is shown with
a GPS receiver. A waypoint can be marked at the cursor
position for later retrieval and use with a GPS receiver.

Route: Two or more linked waypoints that show
intended navigation and the shortest path from one
waypoint to the next.

progress across a given distance, and is the speed
measurement provided by GPS.

Views
The views available on your
Chartplotter are:
• Bird's Eye No Readouts View
• Bird's Eye View
• Bird's Eye Big Digits View
• Chart No Readouts View
• Chart View
• Chart Big Digits View
• Instrument View
• Screen Snapshot View
• GPS Diagnostic View.
NOTE: When you change any menu settings that affect the display, the view will update
immediately (i.e. you don’t have to exit the menu to apply the change to the screen).
GPS Diagnostic View is the default view until GPS communications are
established. At that point, all the other views become available. When the
VIEW key is pressed, the display cycles through the available views. When the
EXIT key is pressed, the display cycles through the available views in reverse
order. Any view can be hidden or displayed as part of the view rotation using
the Views Menu tab. See Start-Up Options Menu for information about the
Self Test, Accessory Test, and GPS Diagnostic Views.

Bird’s Eye Views
Bird's Eye Views - The Standard Bird's Eye, Bird's Eye Big Digits, and Bird's Eye No
Readouts Views show a 3-D, perspective view of the track and the chart’s land
contour from a point above and behind the boat (the eye point). As the boat turns,
the eye point moves to follow the boat.
When you press the 4-WAY Cursor key in the Bird’s Eye View, the position of the
eye point will shift. This allows you to move and turn the eye point so that you can
look off to the sides, or even behind the boat. Pressing the RIGHT or LEFT arrow
keys on the 4-WAY Cursor key turns the eye point right or left, while pressing
the UP arrow key moves the eye point forward, and pressing the DOWN arrow
key moves the eye point backward.
Pressing the EXIT key moves the eye point back to its original position behind
and above the boat.
NOTE: Standard Bird's Eye View and Chart View share the same set of 9 readouts, 7 of which
are adjustable. When you change the readouts display on the Bird's Eye View, you also are
changing them on the Chart View.

Chart Views
Chart Views - The standard Chart, Chart Big Digits, and Chart No Readouts Views
show cartography from the built-in UniMap™ or an optional MMC/SD map for
the area surrounding your current position. The current track (also known as the
position history or breadcrumb trail) showing where the boat has been, along
with saved tracks, waypoints, and the current route (when navigating), are
overlaid on the chart. You can use the 4-WAY Cursor Control key to shift/pan the
chart to another area. You can use the ZOOM (+/-) keys to zoom in and out. You
can use the INFO key to get information on the chart objects near the cursor.
NOTE: Standard Bird's Eye View and Chart View share the same set of 9 readouts, 7 of which
are adjustable. When you change the readouts display on the Bird's Eye View, you also are
