Updating software on GDL 39

The process for updating the software will vary depending on what device you are using with the GDL 39.

If you are using the GDL 39 with:

• A Garmin aviation portable device: the software update will be received through the portable device. The software update for your portable can be obtained through the WebUpdater program.

• An iOS or Android mobile device: the software will be received through the Garmin Pilot application. This is a free download and requires a Bluetooth connection between the GDL 39 and the mobile device. Once the GDL 39 is connected via Bluetooth, open Garmin Pilot and touch the house icon on the top left of the screen, or the three dots on the bottom right with the word "More" > Devices > GDL 39. Under Firmware, select "Check for Updates". If there is an update available, you can select it when it prompts you to do so. More information regarding Garmin Pilot can be found here.

Note: The GDL 39 will only update when connected to an external power source.
