NavData

and User Data Installation/Operation

The NavData card supplied with your GNC 300XL can be installed or removed

when the GNC 300XL 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 300XL will automatically reinitialize. You may

also reinitialize the unit manually by pressing

An optional user data card can be used to make a backup of user waypoints,

routes, etc. and/or transfer information to another GNC 300XL.

To save user data to the user data card:

1. Install the user data card.

2. Rotate

to highlight ‘Save user data?’. Press

to confirm.

The message ‘Saving to card’ is displayed while the GNC 300XL 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 300XL will instruct you to turn the unit off,

remove the user card and insert the Jeppesen NavData card. After this is complete,

the GNC 300XL is ready for normal operation.
