I have a 2016 Ford Edge, with the older USB hub (GC3Z-19A387-C). To deal with a few stability and performance issues, I tried upgrading from 3.0.19052 (with Nav) to 3.4.20196 today; the upgrade was successful, but then I started receiving a “USB hubs are not recognized” error, even after a master reset. Further reading indicates the hub would need to be replaced to be compatible with 3.4.x.
I’m on a tight budget, so instead want to downgrade to the newest Sync 3 software compatible with the hub. 3.3.19052 is the oldest option SYN3 Updater lists; that downgrade was successful tonight, and the USB hub error has disappeared.
However, I’d like to further downgrade to 3.0.20092, because it’s actually newer than 3.3.19052 (by more than a year!). But SYN3 Updater doesn’t list any 3.0.x options, even when I enable the “show old/test versions” option. So, a few questions:
- I assume that an April 2020 3.0.x is better than a February 2019 3.3.x. Am I wrong? What’s the difference between 3.0.x and 3.3.x?
- To proceed, do I need to reformat, like I did to upgrade to 3.4.x? Is that why SYN3 Updater isn’t listing anything older than 3.3.19052 as an option even with “show old versions” enabled?
- If I have to do the downgrade manually, what versions of Gracenotes etc. do I need to install along with the 3.0.20092 app software? It’s unclear from the IVSU database.
