If I want to load something on an SD memory card, how do I proceed, have pushed the SD in the laptop and now send to SD card, copy, or how?

How do you use a USB stick? The SD card works as well.

Then I put the Micro SD card in the Navi, and the Navi recognizes that?

I assume now that you have a Windows operating system and I can explain that to you as well:

Select the files you want to load on your SD card, then press "CTRL + C" to copy the files to your PC's clipboard. Then you change to the folder of your memory card and paste the files in your desired place with "CTRL + V" again.
That's it.

Either send, or copy. Cut out, but then it is gone at the place of origin. The card works like a drive (with letters)

Open Explorer,
Mark file
Destination (SD card) Open folder or main directory
Pull over the marked file

Depends on what you want to copy in there.
Sometimes such a navigation system has a specific folder structure, which must be adhered to.

Yes, if the content of the SD card corresponds to what the sat nav expects.

What exactly did you not understand, or do you intend to do?

Some Navis software is there to update that. You should have mentioned the Navi in your question.
