I have a BMW Navigator V, and want to plan routes using Basecamp; it works when the Nav is plugged into Windows, but it's unuseably slow. I understand I can load the map into Windows and Basecamp will ideally be more useful - but I can't figure out how to do it.
Express shows no options to do this; my Express version just has tiles for my three Garmin devices.
I've searched the forums and the answer is always "use Express" - but I don't see how.
