MAGVAR Database - Every 5 years (updated as described in a
Genesys Aerosystems Service Bulletin)
CAUTION:
Failure to update the EFIS with the correct NavData® causes the IDU
to remain in continual reboot mode and does not allow any display
page to appear.
The EFIS is updated through the ground maintenance function (GMF). To
gain access to the GMF, prior to applying power, slide the slip indicator or
non-slip blank door cover at the bottom-center of the IDU bezel upward to
the first detent position to expose the USB port.
When an update is performed, the following procedures must be performed
separately on every IDU installed in the aircraft.
To update the databases:
1) Load the navigation database (navdata.exe) and obstruction database
(obst.exe) on USB flash drive.
2) With the power off insert the USB flash drive into USB port.
CAUTION:
Always install a valid USB flash drive in the IDU prior to activating
any ground maintenance function. Operation of the GMF without a
valid USB flash drive installed may cause erroneous failure
indications or corruption of the IDU.
3) Turn on power to gain access to the GMF page.
4) Scroll
to
Update Databases
and push to enter.

5) Once each database is loaded, press any button to continue to
complete the process.
