Yep, my not-very-well-stated point was that it would be awesome if you could also have an "iOverland layer" in your favorite nav software as an offline layer. That way you could view iOverland points layered on better maps than iOverland offers all while in "offline map mode". Dunno, maybe gaia already has iOverland data available; I have switched from gaia to
onX recently and am not looking back ;)
BTW - gaia also offers downloading maps along a route which I preferred over drawing many rectangles and downloading. Create a route and let gaia do the work of getting you the offline maps around said route. Great feature!
