1 GENERAL DESCRIPTION
1.1 Scope
The information in this manual is STC approved. Only the equipment interfaces covered in this manual
are within the scope of this STC. Other equipment may be suitable for use with the GDL 69/69A, but use
of such equipment is beyond the scope of this STC – additional FAA approval may be required if
equipment not covered in this manual is used to interface to the GDL 69/69A.
This document describes the GDL 69/69A operating with software Version 2.11, 2.13, 2.14, 3.00, 3.01,
3.02 and later.
Refer to Section 6, Limitations for additional information.
It is possible for installers to seek evaluation and approval of an alternate installation by means of the
field approval process. This manual and all the data contained within may be used by the installer in
pursuit of a field approval.
1.2 Introduction
This manual presents mechanical and electrical installation requirements for installing the GDL 69/69A
and XM antenna (GA 55, GA 55A and GA 57) as part of the G1000 Integrated Cockpit System (GDU
104x), connected to the MX20 Multi-Function Display (MFD), or the 400/500 series displays. (See Table
1-1 for a list of 400/500 series units). The GDL 69/69A can be integrated into a variety of airframes under
an appropriate TC or STC. Each airframe installation may vary. Interconnect drawings and procedures
that are approved by the aircraft-manufacturer should be used during actual installation.
Figure 1-1. GDL 69/69A Unit View
1.3 Equipment Description
The GDL 69/69A is an XM Satellite Radio data link receiver. Two models are available; the GDL 69 is a
weather data receiver. The GDL 69A is the same as the GDL 69 with the addition of XM Satellite Radio
audio entertainment. For display of weather information and control of audio channel and volume, the
GDL 69/69A may be interfaced to the MX20 MFD or 400/500 series units via an RS-232 bus or the
GDU104x via an Ethernet link. Audio volume and channel changes may also be controlled with remotely
mounted optional switches located in the cabin. The GDL 69A is also interfaced to a Garmin audio panel
for amplification and distribution of the audio signal. The XM Satellite Radio antenna receives the XM
Satellite Radio data signal and passes it to the GDL 69/69A.

Revision E 190-00355-02
1.4 Interfaced Equipment
Accomplishment of installation of the GDL 69/69A under this STC requires previous or concurrent
installation of the following equipment. If installing the model GDL 69, a control display unit is required.
If installing a GDL 69A, a control display unit and audio panel is required.

400/500 series units may be connected to a GDL 69A. The 400/500 series units do not have audio
control capabilities, but the aircraft may be provisioned with a GDL 69A and wiring for future
400/500 series upgrade that will provide audio control and display.
1.5 Audio Entertainment Installation Limitations
The GDL 69A XM Satellite Radio audio entertainment may be installed to all passenger locations for all
aircraft on the STC Approved Model List (AML). XM audio entertainment to crew locations depends on
aircraft installation, which must meet requirements of 14 CFR §23.1431(e).
For purpose of this STC, 14 CFR §23.1431(e) requires that each pilot station must be able to hear the
aircraft’s stall warning horn with the entertainment system audio set to the maximum pilot controllable
setting. This also applies to aircraft with a gear extension warning horn. Aircraft which have electric
stall/gear warning may utilize the GDL 69A audio suppression input to turn off the music during an
event. For these installations, the XM audio may be provided to the crew locations.
For aircraft installations with non-electric stall/gear warning horns, this STC does not provide data for
installation of audio entertainment to crew locations. The GDL 69A audio entertainment may not be
wired to crew locations without a separate evaluation that is beyond the scope of this STC. It is possible
for installers to seek evaluation and approval of an alternate installation by means of the field approval
process. Each installation or aircraft type must be evaluated for compliance with 14 CFR §23.1431(e).
This evaluation may determine that the required horns can be heard satisfactorily without disabling the
GDL 69A audio entertainment to the crew.

2 INSTALLATION
2.1 Introduction
This section provides hardware equipment information for installing the GDL 69/69A, cabling for the
XM antenna (GA 55, GA 55A, or GA 57), and related hardware. Installation of the GDL 69/69A should
follow the aircraft TC or STC requirements. For interconnects with the GDU 104x, MX20 MFD or
400/500 series refer to Appendix D of this manual. For installation information on the GDU 104x, MX20
MFD or 400/500 series, refer to their installation manuals.
Installation of the XM antennas is covered under separate Garmin GA Antenna AML STC.
2.2 Pre-Installation Information
Always follow acceptable avionics installation practices per FAA Advisory Circulars (AC) 43.13-1B,
43.13-2A, or later FAA approved revisions of these documents.
Follow the installation procedure in this manual as it is presented for a successful installation. Read the
entire manual before beginning the procedure. Prior to installation, consider the structural integrity of the
GDL 69/69A installation as defined in AC 43.13-2A, Chapter 1 and evaluate the necessity for audio
suppression inputs in accordance with the GDL 69A Audio Limitations in Section 6. Perform the post
installation checkout before closing the work area in case problems occur.
Complete an electrical load analysis in accordance with AC 43.13-1B, Chapter 11, on the aircraft prior to
starting modification to ensure aircraft has the ability to carry the GDL 69/69A load. Refer to Section 2.8
for the power consumption of each GDL 69/69A mode of operation. Document the results of the
electrical load analysis on FAA Form 337.

2.4 Equipment Mounting
2.4.1 Rack Location and Installation
The GDL 69/69A may be mounted in a pressurized or unpressurized location. The GDL 69/69A does not
require forced-air cooling; when mounting, avoid locating the GDL 69/69A near sources that produce
high levels of heat. The GDL 69/69A has two mounting rack options available, the remote rack and the
modular rack for use with the G1000 system.

Installation Procedure

190-00355-02 Revision E
2.4.2 Remote Mount Rack
The remote mount rack can be installed in a variety of locations, such as the electronics bay, behind the
instrument panel, under the seat or behind the rear baggage area. Leave sufficient clearance between the
GDL 69/69A and any obstruction. Install the rack in accordance with AC43.13-2A Chapter 2 Radio
Installations. The remote mount rack should be mounted to a surface known to have sufficient structural
integrity to withstand additional inertial forces imposed by a 1.86 pound unit (1.72 lbs. for GDL 69). If it
is necessary to build a shelf or bracket to mount the GDL 69/69A rack or if is not certain that the chosen
location is of sufficient structural integrity, refer to Appendix C. Refer to Figure 1-2 for the GDL 69/69A
remote mount rack dimensions. The rack can be mounted vertically using four 8-32 pan head screws
(MS35206, AN526 or equivalent.) It can also be mounted horizontally using four 6-32 100° counter-sunk
flathead screws (MS24693, AN507R or equivalent.) Ensure that the rack has a ground path to the
airframe by having at least one mounting screw in contact with the airframe to minimize radiated
electromagnetic interference (EMI).

2.4.3 G1000 Modular Rack
The G1000 modular rack is used to install the GDL 69/69A in the standard G1000 integrated avionics
system rack. This modular rack may be mounted behind the instrument panel or in the avionics bay. Refer
to Figure 1-3 for the GDL 69/69A G1000 modular rack dimensions. This STC covers the installation of
the GDL 69/69A modular rack into the installed G1000 integrated avionics system rack, but does not
cover the installation of the G1000 integrated avionics system rack.
2.4.4 Remote Switches
Installation of rocker switches should be made on a flat surface and located at a convenient location
within the cabin. Each rocker switch installed must be properly marked of its function. Use of rocker
switches vs. toggle switches will prevent the possibility of raising and lowering the volume at the same
time or raising and lowering the channels at the same time. Wire used for discrete switches should be 24
AWG (MIL Spec M22759) and should be routed as appropriate, avoiding kinking or sharp bends. Figure
2-3 shows typical rocker switches.
