INFORMATION SUBJECT TO EXPORT CONTROL LAWS
This document may contain information which is subject to the Export Administration Regulations
(“EAR”) issued by the United States Department of Commerce (15 CFR, Chapter VII Subchapter C) and
which may not be exported, released or disclosed to foreign nationals inside or outside the United States
without first obtaining an export license. The preceding statement is required to be included on any and all
reproductions in whole or in part of this manual.
DEFINITIONS OF WARNINGS, CAUTIONS, AND NOTES
WARNING
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 website at www.garmin.com/prop65
.
NOTE
The Garmin G3X system includes non-TSO certified products that have received no FAA
approval or endorsement. Consequently the G3X system is not type-certificated and is not
suitable for installation in type-certificated aircraft.
NOTE
Unless otherwise noted all installation guidance, requirements, and instructions apply to
one-display, two-display, three-display, and four-display G3X systems.
NOTE
References to the GDU 37X throughout this manual apply equally to the GDU 370 and
GDU 375 except where specifically noted.
NOTE
References to the GDU 45X throughout this manual apply equally to the GDU 450 and
GDU 455 except where specifically noted.

Rev. AM Page iii
NOTE
References to the GDU 46X throughout this manual apply equally to the GDU 460 and
GDU 465 except where specifically noted.
NOTE
References to the GDU 4XX throughout this manual apply equally to the GDU 45X,
GDU 46X, and GDU 47X except where specifically noted.
NOTE
References to the GMC Mode Controller throughout this manual apply equally to the
GMC 305, GMC 307, and GMC 507 except where specifically noted.
NOTE
References to the GSU 25 throughout this manual apply equally to the GSU 25B,
GSU 25C, and GSU 25D except where specifically noted.
NOTE
The term LRU, as used throughout this manual is an abbreviation for Line Replaceable
Unit. LRU is used generically in aviation for a product (such as a GDU 37X or GTP 59)
that can be readily “swapped out” (usually as a single component) for troubleshooting/
repair.
NOTE
All GMU 22 information in this Installation Manual also applies to the GMU 44. The
GMU 44 had previously been used as the G3X magnetometer but has been replaced by the
GMU 22.
NOTE
Connector references JXXX(X) and PXXX(X) are used throughout this document. The
letter “J” or “P” designates the connector (whether on the LRU or wiring harness). “J”
(Jack) refers to the connector on the LRU, and “P” (Plug) refers to the connector on the
wiring harness. “J” or “P” designate the connector only, regardless of contact type (pin
or socket). However GDU 4XX connectors on the LRU are designated as P4X0X.
NOTE
The GDU 37X/4XX products contain a lithium battery that must be recycled or disposed
by professional services according to applicable governing laws. Only Garmin-authorized
service facilities are permitted to perform maintenance on this product.

190-01115-01 G3X/G3X Touch Installation Manual - Inventory of Materials
Rev. AM Page 1-1
1 INVENTORY OF MATERIALS
This manual provides all of the mechanical and electrical information required for the installation of the
G3X system. This manual is intended to be a step-by-step guide to the installation, therefore it is important
that the steps in all sections be performed in order. All materials that are required/optional for the
installation of the G3X are listed in this section (as such, some of the information in this section is repeated
in following sections).
Before beginning the G3X installation, it is recommended that the installer perform a complete inventory
of all materials listed in this section (some materials are optional and may not be applicable to the
installation). Section 1 should be used to verify that all components ordered from Garmin have been
delivered correctly, and to identify any required materials that are not provided by Garmin.
1.1 Unpacking Unit
Carefully unpack the equipment and make a visual inspection of all contents for evidence of damage
incurred during shipment. If any component of the G3X is damaged, notify the carrier and file a claim. To
justify a claim, save the original shipping container and all packing materials. Do not return any equipment
to Garmin until the carrier has authorized the claim.
Retain the original shipping containers for storage. If the original containers are not available, a separate
cardboard container should be prepared that is large enough to accommodate sufficient packing material to
prevent movement.
1.2 Required Garmin Equipment
1.2.1 Garmin LRU (Line Replaceable Unit) List for G3X systems
Table 1-1 and Table 1-2 list the two available G3X System LRU kits. The standard kit includes the
GSU 25 and GMU 11, the performance kit includes the GSU 25 and the GMU 22. Available GDU Display
Units are listed in Table 1-3
. All other G3X LRUs (listed in Table 1-7) are ordered separately.

1.5 Required non-Garmin Equipment
1.5.1 Wiring/Cabling Considerations
The installer will provide all wiring and cabling unless otherwise noted. Use MIL-W-22759/16 (or other
approved wire) AWG #22 or larger wire for all connections unless otherwise specified. The supplied
standard pin contacts are compatible with up to AWG #22 wire. RG-400 or RG-142 coaxial cable with
50 nominal impedance and meeting applicable aviation regulations should be used for the installation.
1.5.2 Contact and Crimp Tools
Table 1-8 lists recommended crimp tools used to build the wiring harnesses for the G3X LRUs, other
equivalent tooling may also be used.
