It's easy to see why I hate this mount. First off, we are powering a GPS, not running NASA. This all-in-one mount not only includes the power wires, but also a audio out for your headphone navigation and also another audio port (in?). Perhaps the best feature of this whole contraption is the female micro USB port which is used to allow you send files to the GPS without undocking it. However, this port is not waterproof and when it gets wet will send all kinds of messages to your GPS which will render it useless as it will cover the entire screen with useless error messages. For all of this joy, you will be $60 dollars lighter in your pocket.
Of note here, in order to get the SAE plug to mate to your bike's connection, the positive connector on your GPS MOUNT is now going to the be exposed pin. There is no harm such as arcing, as it's impossible for this pin to be engerized when unplugged.
