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.
NOTE
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.
NOTE
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:
NOTE
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.
