Sending classified waypoints to a device

Hi guys,
Good night!
Does anybody know how can I send classified waypoints from a list in Basecamp to a BMW NAvigator V?
I tried export in a different files by Basecamp, save diferent files inside the GPS GPX folder, save diferent folders inside the GPX folder ... nothing works
All these ways the points goes to GPS ins unique list

Thanks

I will have to do by hand
