How GPS and Cartography Work
Your 700 Series™ Fishing System also supports GPS and chartplotting, and uses GPS and
sonar to determine your position, display it on a grid, and provide detailed underwater
information. 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 GPS Receiver included with your 700 Series™ Fishing System, allows you to
cosmbine easy-to-use FishingGPS™ chartplotter and navigation capabilities with
advanced fishfinding. The following GPS functionality is currently supported by the
700 Series™ Fishing System 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.
Multi-Media Card (MMC)/SD Slot
Your 700 Series™ Fishing System 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™ Fishing System will
Inserting an MMC/SD
retrieve that chart and display it automatically. Use
into the Card Slot
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.
