Multi-Media Card 
(MMC)/SD Slots

The two multi-media card (MMC)/SD slots on
your control head can be used with MMC/SD
cards (optional-purchase required) to add
detailed charts to your Fishing System, update
your Fishing System software, or export
navigation data from your Fishing System.

To insert an MMC/SD card:

1. Remove the MMC/SD slot cover.

2. Position the MMC/SD card so that the label faces the right side of the

unit, and insert the card into the slot. Press down on the card until it
clicks into place. 

3. Close the slot cover and turn the knob just 1/4 of a turn to close. Do

NOT overtighten, as this will not improve water resistance and may
damage the cover.

To remove an MMC/SD card:

1. Remove the MMC/SD slot cover.

2. Press the MMC/SD card into the slot and then release. The card will

eject from the slot.  

Adding Maps to Your Fishing System

Your 700 Series™ Fishing System includes a built-in UniMap™. You can also
purchase MMC/SD cards with additional chart information for a particular location. 

When you install the MMC/SD cards in your control head, your 700 Series™
Fishing System will retrieve that chart and display it automatically (see 

Multi-Media Card MMC/SD).
