3.2 ReadyBoost

SD cards used in Garmin displays can potentially be harmed by the Windows operating
system ReadyBoost feature available in Windows. ReadyBoost is a disc caching feature
allowing an external flash memory device such as a USB flash drive or SD card to be
used to speed up system operation by writing frequently used PC Data to the external
flash memory device for faster access.
ReadyBoost can potentially overwrite required data on any Garmin SD card installed in a
computer with ReadyBoost enabled and render the card unusable. Garmin advises using
the following procedure to disable ReadyBoost:
1. Plug a flash drive or other removable media device (non-Garmin SD card) into
the computer.
2. In the AutoPlay dialog box under General Options, click 'Speed up my system'.
3. In the properties dialog box for the removable media device, click the
ReadyBoost tab, and then click 'Do not use this device' to disable ReadyBoost.
4. Click OK.

3.2.1 Display Digital Signature Check

If loader card 006-B2634-0(X) is going to be installed, first determine if the G1000 NXi
has had loader card 006-B2633-0(X) previously installed by checking the PFD1
MANIFEST config page or the MFD start-up page in the upper right corner. Alternately,
check PFD1, MFD, and PFD2 displays if any were replaced if they have unit software
versions 20.00 through 20.12 installed using configuration mode and the SYSTEM
STATUS config page.
If display software version 20.00 through 20.12 is present in any display, and loader card
006B2634-0(X) is going to be installed, a display digital signature update card P/N 006-
B3071-01 needs to be installed first. Do NOT install the digital signature update card if
the displays will use loader cards 006-B2633-0(X).
