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.
Page 18: System Overview
The system combines primary flight instrumentation, aircraft systems instrumentation, and navigational information, all displayed on one, two, or three color screens. The G3X system is composed of several sub-units or Line Replaceable Units (LRUs). LRUs have a modular design and can be installed directly behind the instrument panel or in a separate avionics bay if desired.
Page 19 1.3.2 Configuration Modules The G3X system is designed to store configuration and calibration data in multiple locations to retain the configuration of the system during maintenance. Figure 1-2 shows the configuration module that installs on both the GDU 37X (PFD) and the GSU 73 connector backshell.

Considerations document (190-01051-00) available from the Garmin website ( www.garmin.com) The following guidelines describe proper mechanical installation of the Garmin GMU 44 Magnetometer. The guidelines include requirements for proper location selection in the aircraft, requirements for supporting structure and mechanical alignment and restriction on nearby equipment.
Page 36 The heading offset procedure is described in Section 8.3.4. It is strongly preferred that the GMU 44 alignment is within 0.5° of the aircraft longitudinal axis, rather than using the heading offset procedure. Page 3-4 G3X Installation Manual – GMU 44 Revision E 190-01115-01...

The GMU 44 magnetometer has an attached pigtail with male polarity. The harness connector for the GMU 44 has female polarity.
Page 38: Maintenance
If the GMU 44 is ever removed, the anti-rotation properties of the mounting screws must be restored. This may be done by replacing the screws with new Garmin PN 211-60037-08. If original screws must be re-used, coat screw threads with Loctite 242 (blue) thread-locking compound, Garmin PN 291-00023-02, or equivalent.

Locate the GDU 37X as far as possible from all COM antennas. If a COM antenna is found to be the problem, a 1.57542 GHz notch filter (Garmin P/N 330-00067-00) may be installed in the VHF COM coax, as close to the COM as possible.
Page 55 VHF COM or the (re-radiating) ELT transmitter. NOTE The separation requirement does not apply to GPS and COM combination antennas, provided the antenna has been tested to meet Garmin’s minimum performance standards. The separating requirement includes the combination with an XM antenna element as well.

Page 57 Modifications of this sort are not recommended or inferred by Garmin or the installation of the G3X, and the installer should seek the guidance of the kit manufacture for such modifications.
Page 58: Antenna Grounding Plane
The bottom of the antenna does not need to make contact with the ground plane (i.e. the surface may be painted). The antenna will capacitively couple to the ground plane beneath the paint or aircraft cover. Page 6-8 G3X Installation Manual – Antennas Revision E 190-01115-01...
Page 59: Teardrop Footprint Antenna Installation (Ga 55 And Ga 56)
This section describes the structural mounting of the teardrop footprint antenna installation. An acceptable installation method is to use Garmin P/N: 115-00846-10 doubler plate with the GA 55 or GA 56 stud mount antennas. Another acceptable method is to fabricate and install one of three doublers (Figure 6-4, Figure 6-5, and Figure 6-6), depending on the thickness of the skin.
Page 60: Antenna Installation Instructions
Do not use construction grade RTV sealant or sealants containing acetic acid. These sealants may damage the electrical connections to the antenna. Use of these type sealants may void the antenna warranty. Page 6-10 G3X Installation Manual – Antennas Revision E 190-01115-01...

Garmin has included in this manual some installation guidelines to aid the builder in the placement of various units which make up the G3X. It is at the discretion of the builder whether he or she wants to follow a typical layout or design an installation completely unique to their aircraft. The following information is provided as guidance only and does not account for variations in specific installations.
