This month I should pick up my MDX with NAV but I have some concerns regarding unmapped areas. I currently live in a town that is not listed in the detailed areas. Does this mean that I will not be able to choose a street route between myself and say either another unmapped town or even a mapped town? It would seem to me that unless you chose two detailed areas next to each other or you chose a start and destination within a single detailed area this feature would not work. I know that Alpine is planning to include all towns and cities in a 2003 release but until then the Nav not as useful as I once thought?
