Garmin G3X Touch™Pilot’s Guide for Certified Aircraft
190-02472-00 Rev. D
Warnings, Cautions & Notes
WARNING: Navigation and terrain separation must NOT be predicated upon
the use of the terrain function. The G3X Touch
™
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 surround-
ings 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: To reduce the risk of unsafe operation, carefully review and
understand all aspects of the G3X Touch 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 G3X Touch 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: 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 G3X Touch internal GPS receivers is
geometric height above Mean Sea Level and could vary significantly from
the altitude displayed by pressure altimeters. Always use pressure altitude
displayed by the G3X Touch PFD when determining or selecting aircraft alti-
tude.
WARNING: Do not use outdated database information. Databases used in the
G3X Touch system must be updated regularly in order to ensure the informa-
tion remains current. Pilots using any outdated database do so entirely at
their own risk.
WARNING: Do not use data link weather information for maneuvering in,
near, or around areas of hazardous weather. Information contained within
data link weather products may not accurately depict current weather condi-
tions.

Garmin G3X Touch™Pilot’s Guide for Certified Aircraft
190-02472-00 Rev. D
Warnings, Cautions & Notes
WARNING: Do not use the indicated data link weather product age to deter-
mine 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 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.
WARNING: The illustrations in this guide are only examples. Never use the
G3X Touch to attempt to penetrate a thunderstorm. Both the FAA Advisory
Circular, Subject: Thunderstorms, and the Aeronautical Information Manual
(AIM) recommend avoiding “by at least 20 miles any thunderstorm identified
as severe or giving an intense radar echo.”
WARNING: Because of variation in the earth’s magnetic field, operating the
G3X Touch within the following areas could result in loss of reliable heading
indications. North of 72° North latitude at all longitudes; South of 70° South
latitude at all longitudes; North of 65° North latitude between longitude
75° W and 120° W. (Northern Canada); North of 70° North latitude between
longitude 70° W and 128°W. (Northern Canada); North of 70° North latitude
between longitude 85° E and 114° E. (Northern Russia); South of 55° South
latitude between longitude 120° E and 165° E. (Region south of Australia
and New Zealand)
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 G3X Touch utilize GPS as a
precision electronic NAVigationAID (NAVAID). Therefore, as with all NAVAIDs,
information presented by the G3X Touch can be misused or misinterpreted
and, therefore, become unsafe.

190-02472-00 Rev. D
Warnings, Cautions & Notes
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 use the approach information provided by the VFR navi-
gation database residing within the G3X Touch as a means of navigating any
instrument approach. The G3X Touch VFR navigation database is limited to
present only the waypoints for the final approach leg of a published procedure.
These waypoints and associated course line are made available for monitoring
purposes only.
WARNING: Do not rely solely upon the display of traffic information for col-
lision 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.
WARNING: Do not rely solely upon the fuel quantity indications or calculated
fuel quantity. It is the responsibility of the pilot to perform proper flight plan-
ning and verify that indicated fuel quantity values are accurate prior to each
flight.
WARNING: For safety reasons, G3X Touch operational procedures must be
learned on the ground.
CAUTION: The display uses a lens with a special coating that may be
sensitive to abrasive cleaners, etc. CLEANERS CONTAINING AMMONIA OR
SOLVENTS MAY HARM THIS COATING. It is very important to clean the lens
using a clean, lint-free cloth (such as the Garmin cleaning cloth). Avoid any
chemical cleaners or solvents that can damage plastic components.

190-02472-00 Rev. D
Warnings, Cautions & Notes
CAUTION: The Garmin G3X Touch 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: The Garmin G3X Touch 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 G3X Touch. 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.
NOTE: All visual depictions contained within this document, including screen
images of the G3X Touch panel and displays, are subject to change and may
not reflect the most current G3XTouch system and aviation databases. Depic-
tions 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: Interference from GPS repeaters operating inside nearby hangars can
cause an intermittent loss of attitude and heading displays while the aircraft
is on the ground. Moving the aircraft more than 100 yards away from the
source of the interference should alleviate the condition.
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.

Warnings, Cautions & Notes
NOTE: Unless otherwise specified, all screen images contained within this
document are taken from the GDU
™
460display. The GDU 470 screen images
will vary slightly from the GDU 460.
NOTE: The GDU 4XX automatically logs flight data including, but not limited
to, primary flight data, engine parameters, and system status information. This
data can be downloaded to an SD card, when the aircraft is on the ground.
The downloaded data can be viewed using common computer software.
It is not possible to disable the logging of this data or to manually delete
logged data. Logged data will be stored only on the GDU 4XX and will not
be transmitted or transferred to Garmin or to any other third party, with
the exception of government agencies investigating an accident or incident
involving your aircraft and/or the parties to any resulting legal proceedings
that may be related to the aircraft accident or incident.
