Tom Tom 550 - Routes or Tracks, which is better?

Sat Navs treat routes and tracks very differently. Here is how a Tom Tom Rider 550 deals with them and how they are different. Tom Toms own MyDrive system can save GPX files wirelessly to the Sat Nav but they appear as tracks, what if you want a route with all of your waypoints? You must save as an ITN file and transfer to your Sat Nav instead, here's how. (sorry for some poor screen grab from PC footage)
