I installed a 32GB microSD card in my Montana 650t.
So, no what? My previous garmin GPS' allowed you to choose how you wanted the microSD card to be used. Like what to store there etc.
The owners manual shows you how to install one but that is the only mention. BaseCamp doesn't let you choose where to transfer tracks, waypoints, birdseye imagery, etc.
Is there a FAQ on this? I cannot find very much information about the Montana GPS anywhere online. :-(
