CacheTrack Map Preloader 
Now you can preload maps from Openstreetmap.org to be used by CacheTrack.
Just use the
CTMapLoader .
Load the cache(s), select them and let the application download the maps. The maps are compressed and saved as *.CTM files. Copy these files together with your geocaches to your phone's memory card and a new menu item will be available allowing you to load a map from the file system. (CacheTrack 1.6 or better is required)
Hope you like it.
