H.6 SiriusXM® Activation Instructions (GDU 375 only)
Follow the below instructions to activate the SiriusXM receiver in the GDU 375.
Before SiriusXM Satellite Weather can be used, the service must be activated by calling SiriusXM at
1.866.528.7474. Service is activated by providing SiriusXM Satellite Radio with a Radio ID. SiriusXM
Satellite Radio uses the Radio ID to send an activation signal that allows the G3X MFD to display weather
data and/or entertainment programming. SiriusXM service should activate in 45 to 60 minutes.
1. The Radio ID can be displayed by accessing the XM Audio Page, and then pressing the INFO
Softkey. Record the Radio ID for reference during SiriusXM Activation.
2. Make sure the aircraft's XM antenna has an unobstructed view of the southern sky. It is highly
recommended the aircraft be outside of and at least 25 feet away from the hangar.
3. Hook up the aircraft to external power if available. The complete activation process may take 45-
60 minutes or more, depending on the demand on the SiriusXM activation system.
4. Power on the avionics and allow the G3X to start. Do not power cycle the units during the
activation process.
5. Go to the XM Info Page. During the activation process the unit may display several different
activation levels, this is normal and should be ignored. When the service class (Aviator Lite,
Aviator, or Aviator Pro) and all of the weather products for the class that you subscribed to are
displayed, the activation is complete. Wait 30 seconds to allow the GDU 375 to store the activation
before removing power.
NOTE
During the activation process do not change channels or pages.
If the SiriusXM receiver will not receive, an Activation Refresh may resolve the issue. An Activation
Refresh may be performed by visiting the link https://care.siriusxm.com/retailrefresh_view.action
and
following the instructions listed there. Visit http://www.siriusxm.com/sxmaviation
for SiriusXM weather
info.
Test the SiriusXM® Receiver (if applicable):
1. Power on unit and use the FMS Joystick to select the XM Page.
2. Verify the XM receiver is functioning correctly as indicated by the green signal strength bars.
