Detailed Operation
GDL 69/69A Flight Information Service (FIS) Function
The FIS Function is capable of displaying graphical weather information through the XM Satellite Radio Ser-
vice when activated in the optional installation of the GDL 69/69A. A variety of graphical data can be overlaid
on the map at the touch of a button. Review the Limitations section in the front of this guide for the limitations
that apply to the FIS data. To minimize the possibility of display clutter, up to four weather products may be
displayed at any one time. When four weather products are displayed, you must first disable a product before
enabling another.
XM Satellite Radio offers several subscriptions, that are differentiated by the products provided with each level.
Refer to the XM Satellite Radio web site for a description of the subscription options. The MX20 provides options
via the menu item keys for all supported functions, even those that are not available for all subscription levels.
