Mucking about in the air conditioning today and installed a little app on the samsung galaxy S4.
The app is called Androzic, its free and it handles oziexplorer map files which are easy to find. It loads the track files from the nav rides no problems, will leave a snail trail of your ride, drop waypoints and is pretty easy to get the hang of.
Looking for a cheap GPS option or a second GPS for the dirtbike then just take your phone.
I purchased oziexplorer years ago and its quite good as well, harder to use but does more for $25
