Hi Catymag and thanks for your reply. I read the link about creating a virtual SD drive in order to see the map in Basecamp. So it's not just a case of placing the map in a specific folder (such as C:\ProgramData\Garmin\Maps) then? The map must be stored in a virtual SD to be visible in Basecamp? Or does it work if stored on a real SD card?

Is this related to the patched version of Basecamp - ie, does the patched version get around this restriction, or what other features does the patched version allow that the normal Basecamp does not?

Thanks again for your help
