I used the Syn3 Updater to create an Interrogator Log USB. This formats the disk and installs the interrogator tool. I did this before deleting the files and copying over files for the Sync and then NAV update (as shown in my previous reply).
I went ahead and repeated this to have a fresh disk and generate a new interrogator log output. Please see screenshot of the interrogator log output as well as copied information from middle column as it wouldn’t all fit in a screenshot. This is my current setup with updated Sync, SystemVoice and Gracenote from the tutorial.

I tried to do the update once again using a different USB Drive, 32GB Sandisk USB3.0, still no luck. I get the update screen prompt, I select update. I immediately get the SIGN_ERR01 error.
Everything works on my system, just wanting to get updated maps loaded.
