10.7 Navigation Databases
Features
Perspective systems with GDU software version 10.0 and above may utilize the following
database features:
Dual Navigation Database Support: the GDU is able to store an upcoming navigation database
on the bottom SD card so that the system can automatically load it to replace the active
database when the new database becomes effective.
Automatic Database Synchronization: the Perspective system is able to automatically check all
databases stored on the bottom SD cards in each GDU and transfer the most recent cycle of
each database to any cards that do not have the most recent cycle. This gives users the option
of downloading database updates to the database card from only one GDU and letting the
system synchronize the updates to the cards on the other GDU(s).
See the Garmin Pilot's Guide for complete details regarding these features.
Use only blank SD cards to load the Navigation Database into the GDUs. Do not
copy the navigation database (not including Chartview) onto 010‐00330‐42 (or ‐
43) supplemental data cards to load into the GDUs. Doing so may corrupt the
supplemental database cards making them unusable. Replacing corrupt cards is
not covered under warranty.
The navigation database is updated on a 28‐day cycle and is provided directly from Jeppesen.
The navigation database may be installed from the Jeppesen supplied SD data card. After the
navigation database is installed, the card may be removed after loading the update to each
GDU.
Do not load the Navigation Database to a Supplemental Database Card to load
into the displays. SD cards used for loading the navigation database are
formatted differently (FAT) than the Supplemental Database cards (FAT32). This
may corrupt the Supplemental Database Card rendering it unusable. Replacing
corrupted cards are not covered under warranty.
To Upload the Navigation Database:
The following steps are used by both traditional loading of the NAV DB and by
the dual NAV DB (to load the backup DB; GDU 10.0). If the synch feature is also
enabled, this only needs to be performed on one GDU. Otherwise, it needs to be
performed on all GDUs.
