How to Update Your Avidyne GPS Map Database

Avidyne GPS systems such as the IFD440 and IFD540 rely on updated map databases for safe and accurate navigation. Keeping your system current with the latest charts, navigation data, and obstacle alerts is essential for optimal performance and FAA compliance. This guide walks you through the update process.

Prepare for the Update

• An active database subscription (Jeppesen or Avidyne)
• A FAT32-formatted USB drive (8GB or more)
• Avidyne’s Data Transfer Tool or Jeppesen JDM software installed
• Internet access for downloading the update package

Download the Latest Map Data

1. Launch the Jeppesen JDM tool or Avidyne DTT on your computer.
2. Sign into your subscription account.
3. Select your Avidyne GPS model (e.g., IFD440, IFD540).
4. Download the current cycle of map and navigation data to the USB drive.
5. Ensure the USB is safely ejected after the transfer is complete.

Install the Map Update in the Aircraft

• Power on your avionics system and insert the USB into the GPS unit’s front USB port.
• The Avidyne system will detect the update automatically and prompt you to begin installation.
• Follow on-screen steps to confirm and start the update process.
• Do not turn off power or remove the USB during installation.
• When complete, restart the unit and verify that the update cycle is current.

Troubleshooting Common Issues

If the update does not proceed:

• Double-check USB format (must be FAT32)
• Ensure correct database files are downloaded
• Try a different USB drive if the current one is not recognized
• Contact support if you see errors on screen during installation

Stay Current, Stay Safe

Avidyne GPS units require frequent updates to maintain chart accuracy and ensure compatibility with FAA procedures. Most data subscriptions follow a 28-day cycle. You can set automatic reminders or download alerts via your data provider account.
