It has a map of the world, including North America, but when I zoom in to Philadelphia, no streets show up. Waiting on my new BU353(I think I may have fried my old one). Will the street data fill in on its own once I get a signal lock? Got a copy of the program from my neighbor. I guess what I need is map data. USA is not one of the countries I can select to map a route. How can I add maps. Why would they make a program that does not allow you to add new maps as needed? There is no "get maps" option anywhere as far as I can tell.
