I have been unable to transfer any BirdsEye Imagery to the 16GB microSDHC card in my Oregon 450t, using BaseCamp v. 3.0.2 on my Mac Pro running Mac OS 10.6.4. I have tried with the card in the Oregon, and also with the card in a fast USB 2 card reader. (It does have a Garmin folder with a GarminDevice.xmi file in it.)
I had no trouble downloading the Imagery to my computer (although it took a long time!), But when I try to "Send to GPS..." the little gear to the left of my "Oregon 450t..." in the "My Devices" panel begins to spin and the blue and white "Sending..." bar in the "Garmin GPS Transfer" box begins to revolve, but it never changes to a blue progress bar, even after many hours. It should not take 24 hours to transfer a 70MB image, should it?
Any suggestions would be appreciated.
