The spoiler link of osiris4isis works to the GPS forum post and the torrent of 64GB is active with 4 seeds, you need to add torrent raw Hash to Utorrent "can't remember how that was done" I no long use Utorrent, I now use Tixati v2.53. Where I have just placed the raw Hash file.

PM Cserrobi and ask him what countries etc it covers before you continue with this large download.
