You are correct. One cannot simply import a track and then see it on screen. I have tried repeatedly.
However, there may be a workaround where the track has to be re-named to something else like people have done with the Zumo 550s. I have not explored that option personally, but since it seems that one can look back at old tracks, it might be possible. However, I think that for the rider who needs tracks, it is a better idea to get a unit that supports them right out of the box. That would mean Montana (definite), or (I think) the 660/665.
