Insufficient Terrain Database Resolution – The
installed terrain database does not have sufficient resolution
to support HTAWS.
Invalid closest pt of FPL — A closest point cannot be
created from the waypoint entered on the “Closest point of
flight plan” window. This occurs when the selected way-
point is beyond the limits of all legs in the flight plan, too
far away, or when a unique waypoint name for the closest
point cannot be created.
Invalid FPL modification — An attempt was made to
modify the final course segment (FAF to MAP) of an instru-
ment approach. The 500W-series unit does not allow the
modifications.
Invalid waypoint ident — An attempt was made to
create a user waypoint with an invalid name. The 500W-
series unit does not allow spaces between characters in the
waypoint name.
Large magnetic variance — Verify all course angles
— A valid value of magnetic variation is not available for
this location. Check all course angles manually.
Loss of GPS Navigation - Use other NAV if available
— The Dead Reckoning annunciator appears on the left
side of the map display when GPS position is unavailable
and the unit is in Dead Reckoning mode. Dead Reckoning
mode will continue until GPS position is restored.
Loss of integrity — cross-check NAV — The GPS posi-
tion does not meet necessary criteria. Use other navigation
devices to verify your position and navigation.
Low Battery - Unit Needs Service —
Time data may
have been lost due to a memory battery failure
MAIN processor requires service — The 500W-series
unit has detected a failure in the main system processor.
The 500W-series unit is not usable and should be taken to
your Garmin dealer for service.
Near airspace — less than 2 nm — Your GPS-calculated
position is within 2 NM of a special use airspace boundary,
but you are not projected to enter the airspace. This mes-
sage is automatically disabled within 30 NM of an arrival
airport, when an approach is loaded.
No altitude input is being received — No altitude data
is being received from RS-232 (Serializer: Icarus, Rosetta or
Shadin) or grey code inputs. If the problem persists, contact
your Garmin dealer and check the installation and installa-
tion settings.

has detected a failure in the built-in basemap (land data)
memory. Land data does not appear on the Map Page.
Other unit functions continue to work normally, however
the 500W-series unit should be taken to your Garmin
dealer for service at your earliest convenience.
NON WGS84 WPT — Do not use GPS for nav to

not calculated based on the WGS84 map reference datum
and may be positioned in error as displayed. Do not use
GPS to navigate to the selected non-WGS84 waypoint.
Non-WGS84 wpt navigation [xxxxx]. — The position
of the selected waypoint [xxxxx] is not calculated based on
