Radar detector on Navi from Hyundai Ioniq load?

A friend of my father asked me to inform me about this topic. He wants to load a speed camera detector on the Navi of his Hyundai Ioniq. That this is not completely legal, I have learned after an internet search. But it's his responsibility anyway, if he should be checked.

Back to the topic: I found an instruction on the Internet, how to load a speed camera database on the "Point of Interest" on a navigation system. However, the manual is complicated and refers to not fixed Navis. These should then be connected via USB to the PC and upload the data package. But I have only the memory card of the built-Navis at hand.

Does that work too (my laptop has an SD card slot)? Or. Does anyone know any other practical ways to be warned about lightning or has even successfully loaded such a data package on his sat nav?

There are indeed different speed cameras and the software will be installed only stationary speed camera. Mobile speed cameras will be announced on the radio. I could imagine that the warning works.

Yes, I'm only concerned with the stationary speed cameras.
