Hello, Is the AC adapter for the VN QT in one or two pieces? If it's in two pieces, the plug which goes in to the wall is smooth all the way around, and will not fit in either a wall socket or power strip. If it's in one piece, when I plug both ends in to there respective places, I get the message "adapter off", when I check battery status! This is highly frustrating, since I'm at 60% and want to put the GPS through its paces. Any help would be greatly appreciated. Thanks. John Holliday
