I uploaded at home and everything flies without a problem.
The lack of a Polish teacher, but I don't even use the Polish menu, is no special loss for me.
Caution: Supposedly, to upload these maps you need a soft 30 in navigation. I already had it, so I started right away from unlock and then the maps.
If you do not have the software yet, you can download it separately from zaniak (1 post) or immediately with all maps, from me or from zaniak, it does not matter. It is one and the same

Uploading the software for me took about 30-40 minutes, also prepare for a longer meeting in the car or at least next to it. You can leave it, but I preferred to sit and watch :)
Note 2: Of course, we record the unlock on a separate CD. I recorded a very old CD-RW that I found in a box and it works fine. Recording speed x10.
We put it into the drive in the car and then the operation will be looped.
The whole process takes a few seconds, but until we pull out the plate ourselves, one and the same operation will fly over and over again.
It's okay with navigation! You just have to interrupt the operations manually. I stopped like that after a minute of two, I think there were about 5-10 loops, just to be sure :)
Note 3: As for the maps themselves, I recorded them with my program
ImgBurn to the HAWK DVD + DL x4 plate. However, with the cheesy ones, it works. Everything went smoothly, the navigation was updated very quickly!
From what I was looking at, the road cover is already very good for car navigation. Before, I had the V3 version of the maps and it wasn't even my street, and now the whole neighborhood shows up beautifully.
