Hello everyone.
This is my first post. Please bear with me because I am writing through a translator.
I have just purchased a 2017 Ford C-Max. I am angry because I did not check the operation of the Active Parking Assistant when purchasing it.
The problem is as follows:
The Parking Assistant itself works, the car can enter and exit the parking space by itself. However, I do not have any indications on the display. Only the current screen is displayed, e.g. Home, radio, etc. Plus displaying obstacles when approaching them (360 12-sensors).
I searched for a long time and figured out what was wrong. Unfortunately, I do not have contact with the previous owner. I managed to determine myself that Sync 3.4.23188 was installed on the original version 3.0.19205.
I do not know what method was used to update.
Apart from this problem, everything works perfectly, even the radio station logos. Master reset did not help, I do not know where to look for the problem. This is my first Ford 
Searching led me to your forum.

Thanks in advance for any tips.
EDIT:
While writing this post I compared the installed packages with the installer packages for reinstalling sync. I noticed that I am missing APPS NU5T-14G381-AD . Could this affect the Parking Assistant? Maybe I should reinstall the system?
EDIT2:
I must have misinterpreted that.
The integrator does not show it in Installed Packages but it is in version 3.4.23188 (NU5T-14G381-AD)
EDIT3:
While browsing AsBulit from the integrator, I noticed an inconsistency in the BT Vehicle Nameplate ID. The decoder shows that I have Ford Taurus set, while the car is detected by BT correctly as Ford C-max
