Warnings, Cautions & Notes
WARNING: Navigation and terrain separation must NOT be predicated upon the
use of the terrain function. The GDU 37X Terrain Proximity feature is NOT intended
to be used as a primary reference for terrain avoidance and does not relieve the
pilot from the responsibility of being aware of surroundings during flight. The
Terrain Proximity feature is only to be used as an aid for terrain avoidance and
is not certified for use in applications requiring a certified terrain awareness
system. Terrain data is obtained from third party sources. Garmin is not able to
independently verify the accuracy of the terrain data.
WARNING: The displayed minimum safe altitudes (MSAs) are only advisory in
nature and should not be relied upon as the sole source of obstacle and terrain
avoidance information. Always refer to current aeronautical charts for appropriate
minimum clearance altitudes.
WARNING: The altitude calculated by GDU 37X receivers is geometric height
above Mean Sea Level and could vary significantly from the altitude displayed by
pressure altimeters. Always use pressure altitude when determining or selecting
aircraft altitude.
WARNING: Do not use outdated database information. Databases used in the
GDU 37X must be updated regularly in order to ensure that the information
remains current. Pilots using any outdated database do so entirely at their own
risk.
WARNING: Do not use basemap (land and water data) information for primary
navigation. Basemap data is intended only to supplement other approved
navigation data sources and should be considered as an aid to enhance situational
awareness.
WARNING: Do not rely solely upon the display of traffic information for collision
avoidance maneuvering. The traffic display does not provide collision avoidance
resolution advisories and does not under any circumstances or conditions relieve
the pilot’s responsibility to see and avoid other aircraft.
WARNING: Do not rely solely upon the display of traffic information to accurately
depict all of the traffic within range of the aircraft. Due to lack of equipment, poor
signal reception, and/or inaccurate information from aircraft or ground stations,
traffic may be present that is not represented on the display.

Warnings, Cautions & Notes
WARNING: Do not use data link weather information for maneuvering in, near,
or around areas of hazardous weather. Information contained with in data link
weather products may not accurately depict current weather conditions.
WARNING: Do not use the indicated data link weather product age to determine
the age of the weather information shown by the data link weather product. Due
to time delays inherent in gathering and processing weather data for data link
transmission, the weather information shown by the data link weather product
may be significantly older than the indicated weather product age.
WARNING: The Garmin GDU 37X has a very high degree of functional integrity.
However, the pilot must recognize that providing monitoring and/or self-test
capability for all conceivable system failures is not practical. Although unlikely,
it may be possible for erroneous operation to occur without a fault indication
shown by the GDU 37X. It is thus the responsibility of the pilot to detect such
an occurrence by means of cross-checking with all redundant or correlated
information available in the cockpit.
WARNING: The United States government operates the Global Positioning System
and is solely responsible for its accuracy and maintenance. The GPS system is
subject to changes which could affect the accuracy and performance of all GPS
equipment. Portions of the Garmin GDU 37X utilize GPS as a precision electronic
NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, information presented
by the GDU 37X can be misused or misinterpreted and, therefore, become unsafe.
WARNING: To reduce the risk of unsafe operation, carefully review and understand
all aspects of the GDU 37X Pilot’s Guide documentation and the Pilot’s Operating
Handbook of the aircraft. Thoroughly practice basic operation prior to actual use.
During flight operations, carefully compare indications from the GDU 37X to all
available navigation sources, including the information from other NAVAIDs,
visual sightings, charts, etc. For safety purposes, always resolve any discrepancies
before continuing navigation.
WARNING: For safety reasons, GDU 37X operational procedures must be learned
on the ground.
WARNING: The indicators represented on the Panel are based on GPS-derived
data and may differ from the instruments in the aircraft.

Warnings, Cautions & Notes
WARNING: The data contained in the terrain and obstacle databases comes from
government agencies. Garmin accurately processes and cross-validates the data,
but cannot guarantee the accuracy and completeness of the data.
CAUTION: The display uses a lens coated with a special anti-reflective coating
that is very sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS
CONTAINING AMMONIA WILL HARM THE ANTI-REFLECTIVE COATING. It is very
important to clean the lens using a clean, lint-free cloth and an eyeglass lens
cleaner that is specified as safe for anti-reflective coatings.
CAUTION: The Garmin GDU 37X does not contain any user-serviceable
parts. Repairs should only be made by an authorized Garmin service center.
Unauthorized repairs or modifications could void both the warranty and the
pilot’s authority to operate this device under FAA/FCC regulations.
NOTE: All visual depictions contained within this document, including screen
images of the GDU 37X, are subject to change and may not reflect the most
current GDU 37X system and aviation databases. Depictions of equipment may
differ slightly from the actual equipment.
NOTE: This product, its packaging, and its components contain chemicals known
to the State of California to cause cancer, birth defects, or reproductive harm.
This notice is being provided in accordance with California’s Proposition 65. If
you have any questions or would like additional information, please refer to our
web site at www.garmin.com/prop65.
NOTE: Use of polarized eyewear may cause the flight displays to appear dim or
blank.
NOTE: Temporary Flight Restriction (TFR) data is provided by the FAA and may
not be updated outside of normal business hours. Confirm data currency through
alternate sources and contact your local FSS for interpretation of TFR data.
NOTE: The purpose of this Quick Reference Guide is to provide a resource with
which to find operating instructions on the major features of the GDU 37X more
easily. It is not intended to be a comprehensive operating guide. Complete
operating procedures for the GDU 37X are found in the Pilot’s Guide.

SECTION 1 OVERVIEW
1.1 UNIT OVERVIEW
The purpose of this document is to provide a resource with which to find operating
instructions on the major features of the GDU 37X more easily. This Quick Reference
Guide is not intended to be a comprehensive operating guide. Refer to the GDU 37X
Pilot’s Guide and the GDU 37X Installation Manual (available at www.garmin.com) for
complete operating and installation procedures.
WARNING: Do not use the approach information provided by the VFR
navigation database residing within the
approach. The
waypoints for the final approach leg of a published procedure. These waypoints
and associated course line are made available for monitoring purposes only.
GDU 37X
VFR navigation database is limited to present only the
In a configuration which includes an external GPS navigator (i.e., GTN or GNS
Series), the GDU 37X displays the external GPS Navigator’s flight plan and guidance
information. When using an external GPS navigator with the GDU 37X, press the
INTERNAL Softkey on the Active Flight Plan Page or Direct-To Page to make changes
to the active flight plan from the GDU 37X. Press the EXTERNAL Softkey to return to
the external GPS navigator’s flight plan.

NOTE:
The
GDU 37X
internal GPS flight plan is only for VFR use.
Using MapMX serial Data inpUt ForMat
When using a WAAS enabled external GPS navigator (i.e., GNS 430W/530W), and
configuring an RS-232 input for ‘MapMX’ instead of ‘Aviation In’, a more accurate
depiction of the flight plan legs are displayed on the moving map (i.e., holds, procedure
turns, etc). Non-WAAS external navigators do not support MapMX. Refer to the GDU
37X Installation Manual for more information.
EXTERNAL GPS NAVIGATOR FAILURE
In the event that the external GPS navigator fails, the GDU 37X reverts to its internal
VFR GPS for navigation and flight plan modification.
