if you want to get TomTom or Iguidence working with just one click all you need to do is follow this: As the link says you will put the launcher on the root then get rid of the regular tomtom short cout in \windows\start menu\programs\ and replace it with the one in AstroGPSLauncher. Thats it TomTom will fire up with GPS enabled already.
