Hi, I have ordered a GPS antenna to use with a netbook. I am looking for some application that can do turn by turn navigation with multiple destinations ie: point 1 reached, click, navigate to point 2, point 2 reached, click, show me the way to point 3. Im going to have to to a very complicated route including over 100 clients and 400km every day for a few weeks so I need some advice on choosing the right software that can do this in a windows or linux environment. I have an IT background so I can handle more complicated applications or even a combination of applications, all I need is a solution. thank you
