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,

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.

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.
