I am going to keep beating SA15 until I can't use it at all. There is a newer game in town:
Furkot (Free)
It is an online (one strike) but it is pretty good at planning. I have not found how to load additional POI, and it wants you to stop at places it knows. You can tell it to only look for campgrounds, but it does not even come close to knowing about FreeONPs. You can put them in if you know about them. You have to dig into the online (it all is) tutorials to even begin to make it work for you, but it is worth it.
I am still planning to use both SA and the small version of Co-pilot for enroute navigation on non-interstates (where we travel as much as we can).
