Your 700 Series™ supports Navionics® Gold, HotMaps™ and HotMaps™Preimium 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 World map.
Your 700 Series™ uses the optional-purchase 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.
NOTE: MMC/SD cards require an optional-purchase GPS
receiver in order to function.
If you insert an MMC/SD that contains a more detailed chart for a particular location, your
700 Series™ Fishing System 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.

How GPS and Cartography Work
(with optional-purchase GPS Receiver)
With the purchase of an additional GPS Receiver, your 700 Series™ Fishing System also
supports GPS and chartplotting. With a GPS Receiver, your 737 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 optional-purchase GPS Receiver, when used with your 700 Series™ Fishing System, allows you
to combine 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 optional-purchase 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.
