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 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.
