Introduced in version 3.12, Jeppesen Distribution Manager (JDM) for Windows and Jeppesen Distribution Manager (JDM) for macOS can now detect data services on inserted SD/USB media. If this media is inserted after login, or already plugged in before login, JDM displays a prompt that lists the services in the active account that appear on the card. The prompt also indicates if the data is current, out of date, or a future cycle. If any services are out of date, an option to update the service appears. When you click the option, JDM updates all out-of-date services. On completion of this transfer, the automated prompt reappears and confirms that the card is now current.
This Data Validation Pop-up feature can be enabled or disabled in the Preferences menu within JDM.
