3.3 GTN Configuration Mode Overview
NOTE
When configuring the GTN, ensure that no configuration module service messages are
displayed in the message queue. This indicates the configuration module is improperly
wired or damaged.
NOTE
The configuration pages shown reflect main software v6.70. Some differences in operation
may be observed when comparing information in this manual to later software versions.
Configuration mode is used to configure the GTN settings for each specific installation. To access
Configuration mode, perform the following steps:
1. Remove power from the GTN.
2. Press and hold the HOME key and reapply power to the GTN.
3. Release the HOME key when the display activates and the name "Garmin" appears fully lit on the
screen.
The first page displayed is the Configuration Mode page. For detailed information regarding how to
configure the GTN, refer to GTN 6XX/7XX Part 27 AML STC Installation Manual. While in Configuration
mode, pages can be selected by touching the necessary key on the display. Some pages may require page
scrolling to view all of the information and keys on the page. To scroll, touch the screen and drag the page
in the necessary direction or touch the Up or Down keys.
