5.7.8.10 GMX 200/MX20 Interface Check
If a Garmin GMX 200 or MX20 has been connected to the GTN, the interface should be verified as
described in this section.
1. Ensure that the GTN has a 3-D position fix.
2. Create and activate a flight plan on the GTN by touching the Direct-To key and entering a
waypoint.
3. Verify that the RTE and POS data flags are not displayed on the GMX 200/MX20.
4. Verify that the flight plan is displayed on the GMX 200/MX20 using the flight plan (FPL)
function.
5.7.8.11 GDL 69/69A Interface Check
If a Garmin GDL 69 has been connected to the GTN, the interface should
be verified as described in
Section 5.7.8.11.1. If a Garmin GDL 69A has been connected to the GTN, the interface should be verified
as described Sections 5.7.8.11.1 and 5.7.8.11.2. Each of these procedures involves verifying that the
satellite signal is acquired and tracked. Locate the aircraft where there is a clear view of the southeastern
or southwestern sky. XM Satellite Radio satellites are located above the equator over the eastern and
western coasts of the continental United States.
NOTE
The following sections only verify the correct interface of GDL 69/69A to the GTN. It
does not activate the GDL 69 Sirius XM data link radio. Complete instructions for
activating the Sirius XM data link radio can be found in the GDL 69/69A XM
Satellite Radio Activation Instructions, P/N 190-00355-04.
5.7.8.11.1 SiriusXM® Satellite Radio Weather Checkout Procedure
1. With the GTN running in the normal mode, go to the External LRUs page (in the System page
group) then touch the More Info key next to ‘GDL69’.
2. Verify that the Data Radio ID field has a valid ID. For a GDL 69A, the Audio Radio ID field
should also display a valid ID.
3. Verify that at least one subscribed weather product turns green on the GDL 69 status page. This
may take several minutes. This will indicate that the weather products are being received.
4. During SiriusXM activation, “Detecting Activation” will be displayed in the Subscription Level
field on the SiriusXM Information page, and ‘Aviator’ or ‘Aviator Pro’ will be displayed once the
SiriusXM signal is detected.
