Installation Considerations

Fabrication of a wiring harness is required. Sound mechanical and electrical methods and practices are
required for installation of the GDU 37X. Refer to Section 1.6 for wiring considerations, Appendix A.1
for pinouts.
Connector kits include backshell assemblies. The backshell assembly houses the configuration module (if
applicable). Garmin's backshell connectors give the installer the ability to quickly and easily terminate
shield grounds at the backshell housing. The instructions needed to install the Jackscrew Backshell (190-
00313-11), and Configuration Module (190-00313-10) can be downloaded from the Dealer portion of the
Garmin website www.garmin.com.

Mounting Requirements

Refer to Appendix B.1 for outline and installation drawings.
2.7

Unit Installation

The GDU 37X is installed by holding the unit flush with the instrument panel and fastening the four
captured 3/32" hex socket head screws to the panel as shown in Figure B-1.2.

2.8 Continued Airworthiness

Maintenance of the GDU 37X is "on condition" only. Periodic maintenance of the GDU 37X is not
required. Instructions for Continued Airworthiness (ICA) are not required for this product under 14 CFR
Part 21 since the GDU 37X has received no FAA approval or endorsement.
