So I took my GC/310 to a GC Event this weekend. It took a bit to figure it out, but the navigation arrows for the caches were all pointing the exact opposite direction of where I wanted to go. I tried a bunch of settings in Maps, but just can't seem to get them to point the right direction.

So I have been fiddling around a bit since I did the hack. I have some maps. I created one with MOBAC, Downloaded the Maps4Me maps, used the Triton basemap, etc. I'm still working on getting Nt. Geographic topo maps since topo.com has been discontinued, and Alltrails Pro just lets you download GPX files. In doing so, i have found that I can calibrate TIF files (1:24,000 maps) downloaded from the USGS using the MapFinder at http://www.usgsquads.com/ with TritonRMP from http://www.msh-tools.com/triton.html It looks like the USGS did some pretty recent surveys (2010 and 2013 from what I see) so the maps are pretty good. It's just pretty tedious downloading and calibrating the Quads manually. I'm trying to figure out if there is a way to use the GeoPDF files from the actual USGS Map Store since they are already calibrated.... but in my few minutes of looking, I haven't gotten far yet. I've considered investigating RMP format some more to try to write a PHP script to automatically read the data from the .tfw files included in the Zip files and build the RMP, but that won't happen before I go on my trip to the Adirodacks this weekend.

Has anyone been tried this with National Geographic TOPO maps from their software? I was thinking of buying the New York & New Jersey version to print paper maps, but it would be a great perk if it can also load maps into a GC with this mod. I also have MOBAC, but still need to learn more about how to use it. Can that load Esri maps? or should I stick to the OSM Terrain maps. I've worked with both for an online mapping site, and find both good, but sometimes one has strengths over the other
