Garmin 01179, 01178 Users Manual
1 GENERAL DESCRIPTION
1.1 Scope
The information in this manual is STC approved (STC #SA01487SE). 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 2.13 or later, and the optional
GRT 10/GRC 10 wireless remote system.
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 datalink
equipment used to deliver XM WX Satellite Weather™ to a variety of Garmin navigation systems. For
audio entertainment in the cockpit, the GDL 69A also provides XM Satellite Radio. If equipped with the
optional GRT 10/GRC 10 wireless remote system, passengers are able to remotely control the audio
functions of the GDL 69A datalink receiver using the GRC 10 wireless remote.
Equipment needed for receiving XM weather and radio:
GDL 69/69A – (datalink receiver)
GA37, GA 55, or GA55A (XM antenna)
GRT 10 (transceiver) –optional
GRC 10 (remote control) – optional
The datalink equipment will operate with any of the following systems or displays. For a complete list of
equipment see Table 1-1.
400W/500W series displays
400/500 series displays
MX20 Multi-Function Display (MFD)
GMX 200 MFD
G1000 Integrated Cockpit System (GDU 104x)
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 aircraftmanufacturer should be used during actual installation.
1.3 Equipment Description
The GDL 69/69A is an XM Satellite Radio data link receiver. The XM Satellite Radio antenna receives
the XM satellite signal and passes it to the GDL 69/69A. The GDL 69 is a weather data receiver and the
GDL 69A is a weather receiver 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 GMX 200 or MX20 MFD or 400/500, 400W/500W series units via an RS-232 bus or the GDU104x
via an Ethernet link. Audio volume and channel changes may also be controlled with mounted optional
switches located in the cabin or by remotely using the GRC 10 wireless remote. The GDL 69A may also
be interfaced to a Garmin audio panel for amplification and distribution of the audio signal.

General Description
Figure 1-1. GDL 69/69A Unit View
The optional GRT 10/GRC 10 wireless remote system is for use by passengers in the aircraft to control
the audio functions of the Garmin GDL 69A Datalink Receiver. The system consists of two components:
(1) The GRT 10 Wireless Transceiver installed in the aircraft and connected to the GDL 69A serial port,
and (2) the GRC 10 Wireless Remote with an LCD display.
CAUTION
Other transmitting systems which may exist in the aircraft:
Bluetooth and other non-aviation transmitters require separate authorization for use in an
aircraft. If they are present, note that interference from such devices may degrade the
performance of the GRT 10/GRC 10 wireless remote system.

CAUTION
Stow the GRC 10 in a secure location (i.e. glove box, seat back pocket, etc.) when not in
use to prevent damage to the aircraft interior or injury to occupants caused by aircraft
maneuvers.
WARNING
Do not use lithium batteries in the GRC 10.
CAUTION
When replacing batteries, use only new or fully charged batteries. Do not mix new and
old batteries as this can cause battery leakage and damage to the unit. Do not mix battery
types (i.e. rechargeable with non-rechargeable).
CAUTION
Remove batteries if the unit will not be in use for several months. Storing batteries in the
unit for prolonged periods may result in leakage and damage to the battery compartment.
NOTE
Failure of the GRC 10 (i.e. dead batteries) has no impact on normal aircraft operations
and is only used for passengers to control audio entertainment.
NOTE
The USB Port on the GRC 10 is for factory use only.
NOTE
The GRC 10 is paired to the aircraft’s GRT 10 at installation. The GRC 10 will not
control the XM audio functions of another aircraft.

General Description
1.5 Audio Entertainment Installation Limitations
The GDL 69A XM Satellite Radio audio entertainment and optional GRT 10/GRC 10 wireless remote
system 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 discrete 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.
The optional GRT 10/GRC 10 wireless remote system has been tested for interference as part of the STC.
Its operation must not interfere with the proper operation of any required aircraft equipment or systems.
STC installation requires that the installer verify that there is no interference using the post-installation
check-out procedure detailed in Section 4. Operators may use the STC qualification of the device as a
basis for showing compliance with 14 CFR Part 91.21.
