to visually follow a .gpx track, i use #osmin on #linuxmobile if you want to have active navigation on your imported track, use #puremaps (but not possible to just display it)
osmin is nice to see cyclepaths while puremaps is better to display drinkingwater/shelters.
there is also #mepo which, if you can code, could use some nice patches (join the dev channel)!
