W176 HU5S1 Carplay SCN not persistent

[Handed3219]

I am unable to activate CarPlay on my W176 2017 using SCN coding in HU5S1.

Hardware: 2469012507
SW Block #0: 1729023208
SW Block #1: 1769022702
SW Block #2: 2469028004

I have already updated the software via Monaco and DoIP to the version recommended by SW-Finder. After this update, I attempted to change the CarPlay settings within Remote UI Application Write, but these settings are not persistent.

I believe the software version I updated to should support CarPlay. Additionally, I understand that unlocking EZS166 is not a mandatory requirement.

What step am I missing to successfully activate CarPlay?

Above software its a FreshUp_2 Variant of module and it have for sure domain like a = Remote UI Applications Write.

I cannot find FreshUp_2. In Freshup Write, there are no CarPlay options available. In Remote UI Application Write, the CarPlay options are present, but they revert to off immediately after being changed.

Can you provide more detailed information on which step I might be missing?
