•
Check PFD Alert Window for MFD or GDL configuration or software error
messages. Correct any errors before proceeding.
•
Verify that the GDL69/69A software option has been loaded to the aircraft
by the presence of the MFD AUX – XM RADIO page.
•
Ensure the following items are not preventing the audio panel from
distributing XM audio (reference applicable OEM Pilot's Guide for intercom
operation and isolation modes):
•
Verify nothing is plugged into the Music 1 or 2 jacks.
•
Verify the XM volume is not muted on the MFD AUX – XM RADIO
page. Verify the headphone volume is turned up.
•
Verify the COM squelch is not open.
•
Verify the ICS squelch is not open.
•
Verify the marker beacon tones are not being received.
•
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.
•
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 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.
•
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. The unit must be on
and receiving XM to receive the deactivation signal, then the reactivation
signal.
•
Verify that a good ground connection exists through the aircraft between
the MFD and the GDL69/69A unit. Reference the OEM Maintenance
Manual for instructions on how to check bonding and ground points. If
problem persists, replace the GDL 69/69A.
