NavData
®
and User Data Installation and Operation
The NavData card supplied with your GNC 250 can be installed or removed when
the GNC 250 is on or off. Insert the card with the thumb tab at the top, and the
beveled corner at the bottom. If the NavData card is not present when the unit is
powered on, you will receive a ‘No Jeppesen database’ message on the database con-
firmation page, and you will only be able to use user waypoints for navigation. If the
NavData card is removed during operation, a ‘No data card present’ warning will
appear, asking you to reinsert the data card within 30 seconds. If the card is not
replaced within 30 seconds, the GNC 250 will automatically reinitialize. You may also
reinitialize the unit manually by pressing ENT.
An optional
user data card
can be used to make a backup of user waypoints,
routes, etc. and transfer information to another GNC 250.
To save user data to the user data card:
1. Install the user data card.
2. Rotate
O
to highlight ‘Save user data?’. Press
E
to confirm.
The message ‘Saving to card’ is displayed while the GNC 250 transfers all user
data to the User Data card. It may take a few minutes to complete the transfer. When
all user data is transferred, the GNC 250 will instruct you to turn the unit off, remove
the user card and insert the Jeppesen NavData card. After this is complete, the GNC
250 is ready for normal operation.
