I purchased a GPSMAP 64st that was preloaded with topo maps. How do I transfer the topo maps to BaseCamp? I don't want to hook up the GPS each time to my computer to view the topo maps. Thanks.
There are numerous threads on this. You have 2 options. Create a virtual disk and copy the files to that or copy the files to a memory stick or card, Basecamp will read the map files off them.
