Motorola uses magnets to activate car docks, clocks and stuff, this is how it was on the D1and D2 so im assuming it still is. I have a magnet on my wallet and I've accidentally have held the two close together before and activated the car dock so we was experimenting one night. On one side of my wallet with the most magnet strength would activate the car dock and on the other side of my wallet with less magnet strength would activate the clock or vise versa, I cant remember which one did which but u get the point so I could activate the stuff without having docks. So u could possibly test them that way.
