Update 3.0.19205 -> 3.4.26057 reformat with update maps SIGN_ERR02

Hi everyone,

I recently bought a 2016 Ford Mondeo MK5 with SYNC 3 v3.0.19205 and factory navigation (which was working perfectly before I started updating).

I wanted to update it to SYNC 3 v3.4.26057 together with the latest maps.

While writing this post I realized something that might be important: I think my first USB drive was formatted as GPT instead of MBR. Could that have caused any of these issues?

Here is what happened step by step:

I prepared the first USB with reformat and the latest maps.

During the installation I got:

Error in 4U5T-14G422-BBM_1748464677000.TAR.GZ: SIGN_ERR02

From what I have read, this file is one of the navigation voice packages. I don’t actually need all navigation voices since I only use Polish.

After this error, SYNC got stuck on the red reformat screen. I performed a reset (Power + Seek Forward).
After rebooting it was stuck on the “Insert USB” reformat screen.
I created another USB, this time without the navigation voice files, and the installation completed successfully.
However, after that navigation stopped working completely.

Current symptoms:

Every time the car starts I get a message saying that Navigation is not functioning properly.
There is a yellow warning triangle on the Home screen.
In the SYNC “About” menu, the Navigation Version field is completely blank.

After that I also:

Installed Jailbreak and tried a few mods.
Decided to return to a clean installation because I didn’t like one of the mods.
Downgraded to SYNC 3.3.
Then performed another reformat to 3.4.26057.

Unfortunately, the navigation problem is still exactly the same.

My main questions are:

Should I now downgrade to 3.3 again and perform a complete 3.4.26057 reformat with maps, or…
Is it enough to install only the missing maps/navigation files using AutoInstall?
Since my Navigation Version is empty, does that indicate that the map database was never installed correctly?
Can I install only selected map packages and only the voice files I actually need, or is it recommended to install the complete package?

I don’t use the built-in navigation very often because I normally use Android Auto or Apple CarPlay, but I would still like to restore the factory navigation so everything works correctly.

I’ve attached three logs:

  1. 3.0 → 3.4 reformat with the latest maps, which failed with the SIGN_ERR02 error.

  2. 3.0 → 3.4 reformat without any navigation files (maps, voices, etc.), which completed successfully but left the navigation non-functional.

  3. The package and log for the installation I was planning to perform next: installing only the latest maps on my current working SYNC 3.4.26057 using AutoInstall.

Thanks in advance for any advice.

Did you perform a master reset after the upload to the car…if not try that before doing anything else.

Yes, I did.

I performed a Master Reset before starting the updates, and I also performed another Master Reset after the updates were completed. Unfortunately, it didn’t make any difference—the navigation issue is still there, and the Navigation Version field is still blank.
