On CE devices you can save either the track tail or an actual track itself, they get saved with the extension .plt.
To show a saved track on the map, on the main menu tap View then Toolbars then Track Toolbar.
On the track toolbar itself tap the yellow folder, find the desired .plt file, select it, tap Ok & it should then load on the map.
Can have a maximum of 5 shown I think.
Seems a little odd Des didn't include a similar feature in the Andriod version, I've never used it though, only the CE versions.
Track toolbar open at the top of the screen.
Do big things!
