I often commute to work and have no need for communication, music, etc.. It would be quite nice to have a cover or blank to snap into the blue tooth helmet cradle when the actual unit is not installed to provide weather protection. The exposed contacts will likely suffer from exposure to the elements. As an example, Garmin provides a blank to cover their motorcycle mount contacts when a Zumo 660 is not installed.
