Rev. D 

190-00357-02  

NOTE 

The following sections only verify the correct interface of GDL 69/69A to the GNS 

500W Series unit.  It does not activate the GDL 69 XM data link radio.  Complete 

instructions for activating the XM data link radio can be found in document  

190-00355-04. 

5.5.7.9.1  XM Satellite Radio Weather Checkout Procedure 

1.

With the 500W Series unit running in the normal mode, go to the XM Information page (in the 

AUX page group). 

2.

Verify that the DATA ID field has a valid ID and does not contain “---“. For a GDL 69A, the 

AUDIO ID field should also display a valid ID. 

3.

Go to the XM WX Timestamp page and verify that timestamp data is displayed. This may take 

several minutes. (Time stamp data will not be available if the XM subscription has not been 

activated.) 

During XM activation, “Detecting Activation” will be displayed in the SERVICE CLASS field on the 

XM Information page, and “Aviator” will be displayed once the XM signal is detected. 

5.5.7.9.2  XM Satellite Radio Audio Checkout Procedure 

1.

Go to the XM Audio page (in the AUX page group). 

NOTE 

If the XM Satellite Radio audio subscription has not been activated, audio is available 

only on Channel 1.  If the audio subscription has been activated, audio should be 

available on multiple channels. 

2.

Ensure that the GDL 69A audio is not muted. 

3.

Verify that audio can be heard over the headsets.  Adjustment of the volume may be required. 

5.5.7.10  Crossfill Check (If Dual Units Installed With RS-232 Crossfill Connected) 

Turn on both 500W Series units in the aircraft.  For each 500W Series unit: 

1.

Select the first AUX page (titled “FLIGHT PLANNING”). 

2.

Select “CROSSFILL”. 

3.

Verify that the displayed status is “Ready”.  If “Not Available” is displayed, there may be an RS-

232 wiring problem between the two 500W Series units. 

5.5.7.11  External RMI/OBI Interface Check 

The GNS 500W Series unit RMI/OBI output can be used to drive an RMI (or OBI) navigation indicator.  

This check verifies that the RMI/OBI is receiving data from the GNS 500W Series unit.  If the following 

steps do not perform correctly, check the electrical connections and configuration setup. 

NOTE 

The aircraft heading system must be operating properly in order for the RMI needle to 

point correctly.
