Garmin Basecamp displays Garmin Raster maps (such as Alpenvereinskarten or Swiss raster) if they are mounted on a USB stick: ie a Removable Disk.
This is the only way to display them unless you have a Garmin Oregon or other raster map-capable Garmin.
Any one knowledgeable enough to create a Virtual Removable Disk on a Hard Disk Drive, that can be recognized by Basecamp?
Google shows lots of Virtual Drives, but not Removable Virtual that I have been able to be recognized by Basecamp.
This would enable us to store these new Raster maps on a Hard Drive..
