I think that all map data files for GPS are pretty much encrypted to the software that runs them. They do this so that you don't just buy the reader or just the data. I'd imagine there isn't a program that could share this data. BUT! You might be able to find an SDK for the software that runs that maps data. I use the SDK for Destinator 2 and I've written some good stuff for it. However, Destinator 2 sucks and I'm going to order the SDK for Destinator 3. My point (as far as I've moved away from) is that you can use the map data with the SDK that will read the data. Then manipulate the data to your likings.
