Installing and Removing Data Cards
The GPSMAP 276C uses an optional Garmin data cards to display digital charts and maps on-screen
or save user data. Install the data card in the card slots located on the bottom of the unit. Install or
remove the data card at any time, whether the unit is on or off.
To install a data card:
1. Insert the card with the label facing the front of the unit into the slot.
2. Firmly push the card into the unit. It is not necessary to force the card. The handle is still exposed
when it is properly inserted.
3. If the unit is on, a confi rmation tone sounds. The fi rst time you insert a programmed data card, the
unit will take a few seconds to read the card. Once the data card has been properly installed and
accepted, a summary screen noting the card details appears. Press
ENTER/MARK to acknowledge.
If you insert a data card and get a ‘card format not recognized’ message, try removing the card and
reinserting it. If the card is still not recognized, contact Garmin or your Garmin dealer for assistance.
Data cards are not waterproof, should not be exposed to moisture or excessive static charges, and should
be stored in the case supplied with the card.
To remove a data card:
1. Grasp the card handle. The handle expands for easy removal.
2. Pull the card out of the card slot on the bottom of the unit.
3. If the unit is on, a confi rmation tone sounds when the data card has been removed.
