Hey all, I have a Garmin Montana. I have been using OSM maps from Openstreetmap my whole RTW trip so far. I am in France right now and GPS mapless. I downloaded the complete Europe OSM map from Openstreetmap.org and it is 6 gb. (on a 16gig card should work) It took 12 hours to download last night and I don't really want to do every country individually. So. 1. Fat32 has a 4gb limit to file size. No go. 2. I tried NTFS and loaded the .img in the Garmin folder and the GPS did not recognize it. 3. I am about to try exFat but I don't know if that will work with the garmin. 4. Is there a way to split up a img into multiple files? Thanks.
