Ok, here's the problem...
2013 Edge is not Sync 3 or even Sync 2, it's My Ford Touch, the last version for that was 3.10
If your screen is divided into 4 quadrants (phone, climate, audio, NAV/ball compass) or you have a label; "Sync powered by Microsoft" you have MFT.
Sync 3 was introduced on some models in 2016 (eg Escape, F150) and other models in 2017 (eg Fusion).
Go to the General button on the home screen then hit About Sync
If you have Sync 3 lower than v3.2.x the highest level offered by Ford for your vehicle is v3.0.20204.
If you have Sync 3 higher than v3.2.x the highest level offered by Ford is v3.4.23188
Now the question, "can I go from 3.0.x to 3.4.x", officially through Ford the answer would be NO.
That said you can use Cyanlabs updater at your own risk, just remember that a dealer is not going to be able to troubleshoot a bad upgrade, nor will you be able to pull updates directly from Ford's site as you will no longer be on a supported version.
