Running Basecamp 4.0.5 with a new Zumo 660. When the device is connected via USB cable, Basecamp recognizes the device (under "Devices") Lists the map (CN North America NT 2013.30) and displays a loading bar under GMAPPROM. When the loading bar (or process) completes, the device is disconnected from the computer. Without Basecamp running, the Zumo device will remain connected as an established drive letter all day long.
I would appreciate any help understanding how to keep Basecamp connected to my Zumo.
