I have no idea what the previous version was. Probably what was factory installed. Yes, I have the 4.2" screen.
I updated to GC1T-14D544-AB. Prior to this, my iPhone worked as normal and the Ford Edge passed all voice / sound through the Sync Sound System. So I could ask Siri for directions, or where is the nearest Walmart, or what was 2 + 2, or I could dictate a Text or place a phone call...everything would come through the sound system on the Edge.
Now, all I can do is ask directions for a specific location on the street and city. I can no longer ask for the nearest gas station, hands free. i can no longer dictate a text. I need to turn off Blue Tooth to do these things, then physically do them on the phone...not good to do while driving. So pressing the voice button doesn't do anything as Siri works still with SOME functions still coming over the sound systems but it took away others...to which I ask WHY?
So much for Hands Free driving. Which makes me ask Ford...what QA testing did they NOT do to allow there software upgrade to degrade the previous systems functions? They at least should have warned me on their download site this would happen. The upgrade was a waste and gave me nothing that I could see.
As I stated, Ford said they don't post any downgrade software but someone back in 2016 posted that he found software to do that (or reinstall and older version) and posted it on a drop box (which he would give in a private msg). People have asked for it since but that posting is only and closed. Again, so I'm hoping someone knows where to get that software to do this. Doesn't look like anyone has a solution and I'm not paying a dealer to go figure it out.
