If there are any Ford Reps left on this site it would be great if they could provide a download link to an official known good source for 3.10. I went to the owner.ford.com site and the Sync Update page says I am up to date as usual even though I only have 3.8. Most vendors would probably say "if you aren't experiencing issues an upgrade could brick your device" so I get why they probably don't just offer a straight download link.
I did a google search for the filename shown in the wiki article shared by homestead and after trolling around various other Ford forums found one place where someone has shared the 3.10 update file with North American language packs to a cloud sharing service:
So now knowing about the 3.10 update I went ahead and installed it.
Unzip the files (594MB) to a FAT32 formatted USB stick - at the root it has the "SyncMyRide" folder and the USB autorun file.
Start the car in READY mode (there's a nice warning about not killing anyone with carbon monoxide poisoning or starting a fire by parking over tall grass, etc.)
Pull out all other USB devices and insert the USB stick with the update on it
I think it will autorun the install, it restarts the APIM and runs a disk check several times
It turned the radio on (but you can turn volume up/down) during the install and of course several cool SYNC and Microsoft logos appear
The second to final message incorrectly states that you've successfully installed 3.8 - when I checked System Information it was indeed 3.10
All bluetooth devices, navigation favorites and several other prefs are reset to defaults (you have to re-pair your phone)
The UI has a more rounded rectangle look to it
I think maybe using the voice command mic is slightly more responsive.
I haven't tried using NAV yet to see if they were able to improve NAV screen redraw speed
It looks like they may have intended Sync 2 to offer in car WIFI but I don't think my C-MAX has the hardware for it
Siri CarPlay where you hold the paddle in for a few more seconds still DOES seem to work okay
I forgot to check the time I started the upgrade but I would estimate about 15 minutes to go from 3.8 to 3.10.
Of course it worked okay on my car but I should say a reminder that the file is from an unofficial source, I have no guarantee if it works on everyone else's vehicle or not and don't want to be responsible for breaking your car, infecting your PC, etc.
Oh, and I got a notice in the mail today that the A9 navigation map card is for sale through official channel for $149 - it still looks like new map data okay with MFT Sync 2.
