What should I do if I get an LST_005 error when updating my SYNC 3 Navigation map?

An LST_ERR05 error occurs when the navigation maps update license file is not detected within the SyncMyRide folder. Use the following steps if you receive an LST_005 error message while attempting to install your SYNC®* 3 Navigation map update.

Before you start, find your SYNC 3 software version:

  1. Toca Configuración en la pantalla SYNC de tu vehículo.
  2. Selecciona General.
  3. Tap About or About SYNC.
    • If your vehicle has SYNC 3 v3.0, there should be seven files in the SyncMyRide folder. If the JR3T-14G424-CK.TAR.GZ file is missing or has been renamed, you will see the LST_005 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 4U5T-14G424-CH.TAR.GZ file is missing or has been renamed, you will see an LST_005 error when attempting to install the map update.

Adding the Missing License File

If you find your SyncMyRide folder is missing the license file:

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

Renaming the License File

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.

The file name should now be:

  • SYNC 3 v3.0: JR3T-14G424-CK.TAR.GZ
  • SYNC 3 v3.4: 4U5T-14G424-CH.TAR.GZ
