Installation Overview

1.1 Unpacking Unit

Carefully unpack the equipment and make a visual inspection of the unit for evidence of damage incurred
during shipment. If any component of the G3X system 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 Introduction

This manual provides all of the mechanical and electrical information required for the installation of the
G3X system.
The Garmin G3X system includes products like the GDU 37X and the GSU 73 that are
not TSO-certified products and have received no FAA approval or endorsement.
Consequently the G3X system is not suitable for installation in type-certificated aircraft.
The following outline describes the organization of this manual:
