My 62s suddenly isn't being recognized by BaseCamp. When I connect my 62s via USB to my Mac, it won't show up in BaseCamp under "My Garmin Devices", nor will is show up on my desktop as a device. I'm using the USB cable that came in the box with my 62s. I've tried opening up BaseCamp, and then plugging in the USB, and also in reverse order (USB connected, then opening up BaseCamp). My GPS will show the USB icon for awhile, and then power up and show my current location. When I unplug the USB, I get a message saying that I've disconnected from an external power source and asking if I wish to power off the device. I've never had this issue before.
Help! Any thoughts?
