I thought the 86SC came with a BirdsEye subscription. I can download BirdsEye images in BaseCamp with my GPSMAP 86sc plugged in to my PC. When I download another image I get a message that I have to delete the previous image. "Downloading new BirdsEye imagery without a subscription creates a preview BirdsEye imagery. Existing BirdsEye imagery must be deleted from My Collection to continue. The following BirdsEye imagery will be deleted if you continue: [name of previously downloaded image]".
