Actions
No XM audio is heard
No XM weather information is
displayed
a.
Ensure the following items are not preventing the audio panel
from distributing XM audio (reference applicable G1000 Pilot’s
Guide):
•
Verify the XM volume is not muted on the AUX – XM
RADIO page on the MFD.
•
Verify no music sources are plugged into the AUX
music input jack. Verify the COM squelch is not open.
Verify the ICS squelch is not open.
•
Verify the marker beacon tones are not being received.
•
Verify the headphone (if equipped) volume is turned
up.
•
Go to the AUX – SYSTEM STATUS page on the MFD
and ensure unit is online. If a red X is present, verify
the unit is receiving power at the rack connector.
•
Check Garmin service literature for GDL software
advisories. Ensure there are no GDL advisory
Messages in the alert window. If there is an Alert for
software or configuration error or mismatch, reload the
file noted in the Alert.
•
Restart the PFD and MFD in configuration mode and
go to the GDL page. Verify unit is active.
•
Verify the Signal number is “2” or “3”. If it is “0” or “1”
check the GDL 69/69A antenna and cabling for faults.
•
Reseat the GDL 69/69A to verify the coax connector is
fully seated.
•
If unit is not active, contact XM Customer service at to
have a refresh signal sent to your unit. You will need
to provide them the Audio Radio ID (and Data Radio ID
number for XM weather) numbers. Also verify with XM
that the correct Weather package (Aviator Lite or
Aviator) is on the account, and that no traffic service
has been activated against that Radio ID. The unit
must be on for approximately one hour after the
request for the refresh has been sent to receive the
signal.
•
Alternatively, you may also go to XM’s website at
http://www.xmradio.com/refresh/
and enter the radio
ID’s to have a refresh signal sent.
•
If there is still problems receiving weather products
after performing the above step, call XM and have the
account deactivated, and a new account activated to
clear out any corrupt account information.
b.
Verify there is a good ground connection through the aircraft
between the MFD and the GDL69/69A unit. Reference the
Aircraft Maintenance Manual for instructions on how to check
bonding and ground points.
c.
If problem persists, replace the GDL 69/69A.
