All tips and ideas welcome.
This works, I've used it for gps nav:
OsmAnd - Offline Mobile Maps and Navigation
You may want to consider an inexpensive tablet with good battery and gps, as these make a better gps nav device than many phones. The big screen is easier to read, and the big battery lasts longer, especially if you turn it off during long idle periods between distant waypoints.
There are 2-3 other apps I tried which allow pre-downloaded maps. However, they either are not free, downland huge maps (whole USA vs individual states), and/or do not permit you to locate large map files on sd memory card, thus using-up all your device's memory.
