Hello, before moving forwards, what’s your end goal?.
If it’s going to 3.0, try reading this guide → Two Step Installation for Sync 3.0 Versions (2.3 thru 3.0) from Sync 3.0 Early Versions (1.0 thru 2.1) Maintaining CarPlay
The key step in that guide is installing 2.2.17011 before moving forward, you can try just installing that first. There’s a post that can help you with just that → 2016 Mustang Sync3 1.0 updated to 3.0 and no Apple Carplay! - #10 by SaNdMaN (you can now download the autoinstall.lst file for that file from that link).
