My upgrade is scheduled shortly, and if there's anything I need to test, tell the dealer, etc.....

Thx all!
I've been back to the dealer. For the both the initial installation and the 2nd visit, they kept the car for several days. The issues still have not been resolved. Right now the upgrade only added remote start, lock, and unlock. I don't get charging status, range or location data. The dealer suggested it was a Fordpass issue. I don't know, just tired of dealing with Ford's shitty dealer network and lack of software support.

Looks like Ford released a new calibration for the modem: HJ5T-14G139-UN. The previous version was "-UM." I'm going to update in Forscan and see if it fixed my issues with range, charging status, etc.

Or maybe not. I keep getting a service procedure interrupted message in Forscan. Guess I'll just have to continue dealing with the limited functionality in the app.

It took 2 hours for the update from -UM to -UN. I turned off screen savers, power management, etc, so that the update could proceed uninterrupted.
Check if you have a screen saver running. Check if your power settings are set to change after a certain amount of time.
I use the maximum performance power mode and set everything to Never shut off or go to sleep. I also am on the AC adapter.
And.... I use a 12V battery charger attached to the 12V battery, because the car will go to sleep per se. The 12V battery charger will keep enough current available for the respective systems to stay operational when the car "sleeps". Again, its 2 hours. A sickly 12V battery could drop well below 11V after 2 hours of powering the still active systems.

My upgrade worked the first time, albeit I had to wait a few days. I did shop around a bit, see if any dealers around me sounded like they knew about the upgrade, and did mine at a dealer that sounded like they had already done an upgrade before mine.

At this time at least on the C-Max side the move from UM to UN doesn't have any visible/noticable changes. Just an FYI. Ford has basically halted these modem upgrades to fix some software issues on their end regarding all this.

Re: AT&T sunset and MyFordMobile app

My FFE is under the knife at the dealer getting this done.

2+ days have gone by without a peep. I told them to take their time....however a little update would be nice. Going to call later today if I haven't heard anything.

Your experience sounds like mine. Days with no update. Hopefully it works when you get the car. I suggest not leaving until you can confirm it's working.

What should I expect to work immediately, vs stuff that will take a day or two to "sync up" ?

If it's not programmed correctly, I believe it will still let you activate but it will not let you remote start or lock/unlock.
