Thanks for the log.
So yeah, you are on the latest 3.0, so we are good there.
About the XML file, you could update that to Ford’s server for them to acknowledge the update was installed.
Now, if you want to update the maps on 3.0 you can, but you will have to manually create the USB (if Ford does not provide it for you).
Important: 3.0 maps are not compatible with 3.4 and viceversa.
Should you choose installing the maps for 3.0, you will have to follow this guide: Tutorial: Sync 3.0.20204 with 2022 EU 2.21 (F11) Map Installation
Yes, you can. Keep in mind you can’t go back to 3.0 though.
