I tried it during the middle of the game where the terrirories aren't useable. When you leave Los Santos you lose the territories, they don't show up on the map. You only regain them when you go back to LS. I think that may be why it didnt work for me on PS2. I'm going to try again after ive done the storyline missions and regain territories in LS. Hopefully it will work for me cause i'd love terrirories all over the map.
