It works, hurray ... as I progressed ...
(I have Galaxy with MCA radio without Converse, I already have SP2015 there, before there were origo maps from 2011)
Preparation:
a) PATCH burn ISO unpacked to CD at maximum speed 8
b) unpack maps and upload to any SD card (prod_info.txt on SD and "cryptnav" folder)
c) find the radio PIN
In a car:
1. Remove the old SD card
2. turn the key to the position before starting (in this position it is going), do not start (maybe even with the car started, I have not tried)
3. I put the CD in the drive
4. the SW version screen was displayed, I clicked the "Next" button (to the left)
5. 10 minutes of waiting (black screen with two gray "earthworms")
6. 7 minutes waiting (gray screen with green-red "earthworm")
7. 2 minutes waiting for automatic radio restart (really done by yourself, wait)
8. Radio PIN request
9. Insert SD card with maps
10. Navigates it
11. tune the radio again
Navigates in Czech (it is in the map and not in the patch).
I took the picture, but I suppose it's not necessary to stuff it here.
Edit 9.4.2019:
Navigates fully in Czech, I had to choose another language and then back to Czech ...
