Reverse Camera Calibration on W246

[stanko11]

I was stupid enough to reset the rear view camera calibration on my W246 and now there is no tire projection on the screen. Is there a way to fix this without a calibration device?

At initial commissioning and after replacement.
Rear view camera control unit or trunk lid/trunk door.
The rear view camera control unit must be recoded using the diagnostic tool.
Calibration of the rear view camera control unit is performed automatically after commissioning.

When I tried to do this, the system calibrated the steering wheel: center, left, right, center, but after that it asked for a calibration device using these images and I was stuck there.
If I do this without it, the calibration will simply fail and I will have to redo it.

We printed out the target on a printer and calibrated it. How to position it is indicated in Xentry.

I finally took it to the dealer but they only charged me for diagnostics and I couldn't find the right size "calibration device".
