Well...
In the IPC, this are things that I have by default, but there is a possibility to have this on your APIM (SYNC3 screen) aswell, so I activated those with Forscan.
I have everything from the list on my car, but some can be activated to see them aswell on the SYNC3 screen and some stay grey after activation to see them on your SYNC3 screen and cannot be used by touching it on the SYNC3...
-----------------------------------
Last night until 11:30 pm I was talking to a person via Discord about the error I had when I tried to activate WWA [got pre-collision error and cam (IPMA) error], but eventually, I received the solution from that person.
Tonight (Tuesday 26 April 2022) first tried those solution on my parents' car (have older IPMA, which I have already upgraded in terms of hardware, on their Fiesta MK8), by changing certain things in the IPMA with Forscan, it finally worked to activate this function, which they and I will probably never need, without an error message...
Then afterwards, tried the same solution on MY car and where I always immediately got an error message in the past, I succeeded in activating this function.
Movie about the feature on a FOCUS, but it works on a FIESTA aswell
So
GREAT Success!
