See that collar around the ball joint on the back of the phone compartment? You loosen that a bit then the ball joint separates easily. And they're easy to loosen or tighten even with gloves on. Oh and I really must stress just how much rain mine had to put up with The BMW's speedo didn't work properly for the first year I had it, so my phone had to be on permanent GPS speedo duties. So in other words I did ~10,000 miles of riding with that mounted on my bike. Seeing it rains something like 30% of the time in England (I vaguely skim read some official looking thing to get that number), that's 3000 odd miles of unending rain without a drop getting inside. Pretty darn waterproof!
