Unfortunately you are better off using your mobile phone or portable sat nav,sadly updates for the first generation IS 200 have since stopped, when I sold my lS200 sport navigator (which I owned for 8 years)two years ago the latest disc I had in it was a 2011 version,furthermore technology has moved on a lot and its pointless making disc when there's no demand,having said that you might find one on the bay but they would be fairly old,hoping this helps
