I would start here, if it has updates available I don’t imagine it will drastically change the experience because of hardware limitations but you can look through the update to see what it does
To change just the maps without an update would be a bit more involved comparing the new version to the old version, finding where the maps are stored and spoofing the update
But if I were you then I would wait until someone more knowledgeable comes around
