Navcore for an old Go500

Hello everybody, first of all thanks for the efforts of this team.
I have an old Go500 with 32 mb which still works with Navcore 8.455. I would like to upgrade the Navcore to a 9 version in order to use newer maps. Which version do you advise for me? I've tried the Universal Navcore Installer and it apparently works but I experienced a few issues (a few restarts and a freeze).
Can you please advise?
Again, thank you.

If you select a version with memory boost it will work just fine, although you might have to edit the reskin file manually for a X20 or X30 emulation.
