Well, I attempted to update the sync system after logging into my account - extracted zip file like I have in the past, with the 2 files at root level of the usb and the syncmyride folder at root level also - tried twice and each time I got the message that installation failed almost immediately - be curious to see if anyone else encounters this issue also before I call support
Hi JCB. Sorry to hear you had issues
Was just coming on to let those interested know that I had a chance to install the update this afternoon.
It went very smoothly. Took less than 20 minutes. If I recall correctly, the instructions stated it could take up to 40 minutes.
In past updates, I would receive several false/premature “Your update is complete” messages. So I’ve learned to wait at least 10 minutes after any messages appear, in order to ensure the update does not restart/continue. However, this time the first “Update complete” message was the last. In this case, I kept driving to my destination...over 1 hour total, and received no more messages.
So when I got home I removed the USB, turned off the car, opened and closed the door, and when I checked my installed SYNC version, it had updated to “SYNC v3.0.23219”.
Back to your issue, JCB: The instructions can be confusing. For SYNC 3, we need to format the USB to
exfat (not fat32). Did you format to exfat?
And as I’m sure you know, the instructions state to download the update to our computer first (not the USB drive). Then unzip the file. Then transfer the unzipped files to the USB etc.
Concerning any noticeable changes to my system after the update was completed? I did not drive long enough after the update was completed to notice. I can only say my system was still working.

The update most likely is only bug fixes and stability updates for various reasons (i.e. new iOS and Android versions etc.), not new features. Again, just my opinion/guess.
EDIT- Forgot to add:
Previously…there had been an XML file added to the USB after we updated, which we then needed to upload to the Lincoln SYNC 3 update website, in order to inform the Lincoln system we had updated.
Present day: While I did not see the Lincoln SYNC 3 update website mention this change (it is possible I missed it), the added file is now a "Microsoft Edge HTML Document". It is located in the "SyncMyRide" folder. When I proceeded to upload that file to the Lincoln SYNC 3 update website, in the same manner as the old XML file procedure, the system accepted it and updated my SYNC version to SYNC v3.0.23219.
If anything I wrote above is confusing, feel free to ask for clarification.
I’m sure others will have more advice and suggestions, so keep us updated and good luck.
