So, I am very satisfied with the docking station. It has three terminals: - Power Supply (invites HD2 and / or second battery) - Synckabel (USB connection to PC) - Audio-out It can always be all cables plugged. It does not have the power supply cables are pulled when the Synckabel used. There is no change-over switch and it is not required. Through the audio jack, the HD2 is stable in the station. The removal is easy. Plugging is 'ne' matter of feeling ". Finally, a word about the optics: The station it is not cheap and is well made. However, the hinge of the battery cover is a little hakelig.
