How do I resolve SYNC 3 Navigation update errors?

The Navigation map update requires a SYNC update before installation.

Update your system to the latest SYNC version via Wi-Fi® or a USB drive and install the Navigation map update again. 

If your vehicle shows Software version 3.0, and you are still experiencing issues, contact the Ford Customer Relationship Center using our Live Chat option or by calling 1-800-392-3673. See the What SYNC version do I have in my vehicle? topic to learn how to find your SYNC software version.

Your vehicle's SYNC Software may not be the latest version. Verify that SYNC is the latest version.

Update the SYNC software, and try installing the Navigation update again. 

If your vehicle has the latest SYNC version installed, and you are still experiencing issues, contact the Ford Customer Relationship Center using our Live Chat option or by calling 1-800-392-3673.

The SYNC module has been replaced recently in your vehicle and the Map License file is incorrect. For assistance, contact the Ford Customer Relationship Center using our Live Chat option or by calling 1-800-392-3673.

Find your SYNC 3 software version:

1. Choose Settings on your vehicle's SYNC screen.
2. Select General.
3. Choose About or About SYNC.
   • If your vehicle has SYNC 3 v3.0, there should be eight files in the SyncMyRide folder. If the license file JR3T-14G424-CL.TAR.GZ is missing or has been renamed, you will see the LST_ERR05 error when attempting to install the map update.
     If your vehicle has SYNC 3 v3.4, there should be 15 files in the SyncMyRide folder. If the license file 4U5T-14G424-CJ.TAR.GZ is missing or has been renamed, you will see an LST_ERR05 error when attempting to install the map update.

When you find that the license file is missing:

1. Find the map license key zip file, which is Download #3 in the download instructions you received after purchasing the SYNC map update.
2. Drag and drop the zip file to the SyncMyRide folder. The file must remain zipped.
3. Try to install the update again.

If the file is not missing but appears with a number in parentheses, such as JR3T-14G424-CK (1).TAR.GZ or 4U5T-14G424-CH (1).TAR.GZ, rename the file by removing the space, parentheses, and number.

If the above steps do not resolve the issue, contact the Ford Customer Relationship Center using our Live Chat option or by calling 1-800-392-3673.

If you receive this error, the USB drive, also known as a thumb or flash drive, is still inserted into your vehicle's SYNC system after the installation is completed.
