I was wrong.  I am not using Drive.  I have iPad connected to the 20/20.  If I want to save it to a thumb drive, I need to export info.  I called Climate this afternoon.  The gal was able to log onto my iPad remotely and looked around at my settings.  She said if I hook up to my 20/20, the maps should rebuild correctly on my iPad.  Otherwise, I need to call back.  The can see the info is saved in the cloud, so my info is not lost.
