No XM audio is heard
No XM weather information is
displayed
•
Ensure the following items are not preventing the audio panel from
distributing XM audio (reference applicable G1000 Pilot’s Guide):
o
Verify the XM volume is not muted on the AUX – XM RADIO page
on the MFD.
o
Verify no music sources are plugged into the AUX music input jack.
o
Verify the COM squelch is not open. Verify the ICS squelch is not
open.
o
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.
o
If a red X is present, verify the unit is receiving power at the rack
connector.
o
Check GDL software version for the following conditions –
o
If 2.99 or less follow instructions in Garmin Service Advisory 0538
for reactivation.
o
If software version is 3.02 or less, see Service Advisory 0613
concerning storm cell limitation that could cause the GDL to stop
sending data to the MFD.
•
Ensure there are no GDL alerts 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.
o
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.
o
Reseat the GDL 69/69A to verify the coax connector is fully seated.
o
If unit is not active, contact XM Customer service at 1-800-985-
9200 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.
o
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.
o
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.
o
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.
o
If problem persists, replace the GDL 69/69A.
