This indicates an invalid request or info from the IPC. This is likely due to the IPC asbuilt configuration error which the APIM is not happy with.
If you changed the asbuilt in the IPC, look to see that it is consistent with the asbuilt in the APIM as far as features, etc.

that's weird because the only thing I've changed on the IPC is RMIE and cruise control

Or either way.

this is the default asbuilt data according to my vin code on the motorcraft website
the ipc database doesnt say what the last two numbers of 720-01-02 and 720-01-04 mean, which is the main difference between the default and my config..

set the RMIE to disabled and see if the DTC clears.
RMI Emotive (RMIE) should be enabled
RMI Entertainment (RMIE) should be disabled

I've had this error before enabling RMIE
also even if that was the main issue then i'd rather have the dtc

OK, then it's likely not that, but you should have the 88B4 coding there.

wish i had the info about what B4 is
i did reset the values to default today
and it changed from B4 to whatever it is now

B4 is just a checksum. No value other than that. The last 2 digits at the end of each code line are checksums.

I see
so it's not a problem to have that DTC
if it was RMIE i mean i like having RMIE so
very unfortunate that i cant have a digital speedometer

720-01-02 has a different metric display unit selected which could cause this message, IF that data is being sent to the APIM. 2F60 vs 2860.

*Set Speed, Cruise Control Menu, English(E)- Metric(F) Display Unit
720-01-02: xxxx-xFxx-xxxx
About that, what's the difference between English and Metric
English i assume is mph
while metric is kmh?
i'm a km user.

This needs to be consistent with the APIM setting.

which exact apim setting?
the only change in the apim is the country code
5553 -> 4747
I will change the metric unit to english but I have yet to find out what that changes

4747=Georgia. I was thinking UK, so maybe the English setting will not be correct.

English is the default option on my car
which is a US car
so that's a bit weird but i would think it has something to do with the cruise control speed adding 2 kmh instead of 2 mph
but whatever i'll change it to english as it was
I'll change everything to default values and see if the DTC clears off.
Now for the other question
These are the changes I did for the region but my Sync 1.1 still doesn't have EU languages
I tried this on a Sync 3 system and it added EU Languages
does my apim need reprogramming?
to get for example German or Dutch

Looking thru the C-Max info I have; your IPC is likely older than some of the options for changing regions. The asbuilt goes to 720-01-04 for yours, where the later versions go to 720-02-02 and accommodate region changes. Your IPC only differentiates between English and Non-English (Spanish/French).
As far as the APIM, I know the early Sync versions did support EU languages, but I need to look that up.

Can I get 720-02-0x if I update the firmware?
but no I won't risk updating the fw
let me know what you'll figure out

To get the option you would need to upgrade the firmware in the IPC, which is not without risk. It would be easier to replace the IPC with a newer version.

yeah..
