If you put in VIA points you can force it to take you on the route you want. Kind of a pain but streets and trips has the same issue.
This is a "feature" not an "issue". The devices or programs have no idea how you would like to go without you giving that input. Some GPS devices won't allow this.
MS Streets and Trip can export a gpx file which I upload to my Garmins. The Garmins may vary slightly between specified route points if they are far apart and there are multiple roads for the unit to choose from.
