However, most USB drives that can be formatted using FAT32
will be acceptable. Alternatively, replacement fobs can be
purchased directly from Avidyne.
To perform a data update, ensure the data to be updated is

IFD in maintenance mode (see Maintenance Mode section on
page 6-53).
Maintenance mode is organized similarly to flight mode using a

Update tab will already be selected.
