What do 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. Tap Settings on your vehicle's SYNC screen.
  2. Select 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-14G242-CF.TAR.GZ" file is missing, you will see the "LST_005" error when attempting to install the map update.
  • If your vehicle has SYNC 3 v3.3 or SYNC 3 v3.4, there should be 15 files in the "SyncMyRide" folder. If the "4U5T-14G424-CD.TAR.GZ" file is missing, you will see an "LST_005" error when attempting to install the map update.

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. 

    Note: 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 Live Chat option or by calling 1-800-392-3673.
