Multi-Media Card
MMC/SD Slot
Your 500 Series™ Fishfinder 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 Fishfinder will retrieve that chart
and display it automatically. Use the illustration to
locate the position of the MMC/SD slot cover, and
use a Phillips head screwdriver to remove the MMC/SD slot cover, then insert the
MMC/SD into the slot. The label on the MMC/SD should face toward the front 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 the screws snugly - do NOT
overtighten, as this will not improve water resistance, and may damage the cover.
