Continuing my newbie trek into the world of GPS, first I reviewed some hardware for the Treo 7xx series and now I'll take a look some software, namely OnCourse Navigator 6 (OCN6) - $89.95. How did I fare with this admittedly simple-to-setup GPS solution?

OnCourse Navigator is just about as *simple* as you can get for setting up a relatively sophisticated GPS software mapping solution on your WM device. One caveat though: it only supports 320x240 or 240x320 resolution, which means square 240x240 Treo screens are, regrettably, excluded from this otherwise excellent software (**Update:** WMExperts now carriers this version which is compatible with WM Treos)

What do I mean by simple? Read on below...
