Firstly, I know very little about iPads; I don't have one - yet. I'm thinking of buying an iPad 3 primarily to use for countryside mapping. The high resolution display would be great for reading maps on. The first catch is it needs to work offline, with maps preloaded into memory. No data connection for quick-fix GPS, just GPS alone. The second catch is that I need to use custom maps, most likely created by Mobile Atlas Creator (MOBAC) on a PC. Now, I've found an app called Galileo that says it caches maps for offline use (nice, but not the maps I need), and can use MOBAC-created maps with an in-app purchase. Does anyone use Galileo and can comment on if the system works nicely offline and with custom maps? Do such things as route navigation and trail marking work? Any other suggestions welcome too, if there is anything better I would like to know. I'm operating on a tight budget so can't afford expensive commercial packages though. The iPad purchase would almost clean me out. /Rick.
