Running BaseCamp 4.1.2; Garmin Colorado 300
I have used this combination successfully for some time. Suddenly my Colorado would not be recognized by the Mac. The SD card could be seen, but not the main Colorado memory. Plugged the device into a Windows machine and it said that it found problems and repaired them. Plugged back into the Mac and now the Colorado could be seen and written to. I have run the Disk Utility and it says that there are no problems.
Now when using BaseCamp - either starting without the device plugged in or without - as soon as I connect the Colorado it starts communicating with spinning arrows under "My Garmin Devices" and never stops. I cannot send or receive from the device because it says it is "busy".
Is there a way to get BaseCamp to stop trying to communicate? I suspect that there is a subtle problem on the device - bad sectors or something - but BaseCamp is not handling it well...
Any ideas?
