So I updated and I found that when muting now it doesn't display "mute". Also when I found the update on this forum and updated it no longer displayed climate control "fan speed" and hasn't been fixed in this version either so my guess is Ford have either removed it or this is a firmware issue. Can anyone else confirm whether or not they have these issues please?
Is it possible to downgrade?
Yes, I can confirm that the Display no longer shows "mute". But it does display the "fan speed" and the "temperature" on an automatic HVAC like normal. Maybe you need to enable "EATC repeater display" in the ACM module via UCDS or forscan.
