I think I'll stay on 2.2 and just insert new maps.
Thank you very much for the detailed explanation and of course for the new maps

can you post a link to unlock iGO navigation please?
2.2.19.300
Thank you very much

Download mm2014_upgrade_igo_2.2.19.300_mod.zip from published link. Copy file on USB stick in folder R-LINK. Procedure is the same...
Then you can upgrade maps 

Greeting
  , I installed everything I need, but a small problem arose.I don't have enough space to upgrade the folders.
I took the TomTom2022.06 that you posted on the link I still have TomTom2022_06-Part4.sku 1.6gb left, but it tells me that there is not enough free space for installation.
Can I somehow delete some unnecessary maps that I will never use?
Some errors also appeared.Can I reset and try again?
If I can how? Thank you

OK

Goran, I suppose you are somewhere from Adriatic region. I can provide you package to delete maps of Russia, Turkey, Cyprus, Belarus, Georgia, Moldova... and French overseas lands (Martinique...)
Another step is to provide you package (I have built Here for myself) which does not contains this countries.

Do you have any cloud storage to upload this stuff?

Another workarround is to separate skus and md5 files; one sku and md5 at a time to install..

Greetings.
First I tried to install everything at once, but there was no space, then I separated one by one, but still there was one that there was no space for.
What happens if I now try to install the shorter version of the map again, do I have to delete it first or return it to its initial state to gain space or simply just install it?
I don't have cloud storage
I tried to remove unnecessary cards myself with SKU creator, but I didn't succeed with this version that I downloaded from your link.
What card format do I need to have in order to be able to put it together in the SKU creator?
Thank you very much for your help
