TopoActive na us 2025.10 updated on my GPSMAP 64sx, ERRORS OUT when trying to view in Basecamp. Will not display. Have reinstalled on my device three times but always the same error (note: Middle America and Canada/Alaska display normally)

Are accessing the map via your device?  Some maps are split into two files on devices.  Devices can handle multiple maps, but BaseCamp can only handle one active map at a time.  If this is the case, the Map Products in BaseCamp will show two TopoActive 2025.10 products.  One will cover the continental USA and the other will cover Canada/Alaska and Middle America
