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.

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.

Rev. AC Page iii

NOTE

References to the GSU 25 throughout this manual apply equally to the GSU 25B 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GMU 44 had previously been used as the G3X magnetometer but has been replaced by the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.

NOTE

The Bluetooth® word mark and logos are registered trademarks owned by Bluetooth SIG,

Inc. and any use of such marks by Garmin is under license.

190-01115-01 G3X/G3X Touch Installation Manual - Inventory of Materials

Rev. AC 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
