That's a wild dock. But like many others, they don't mention how it gets power from the car.

I got the idea to hardwire mini USB from ProClip, with their integrated charging cable. I could use a mini USB cable hardwired to the car to power the BlackBerry Bluetooth gateway, then tuck the whole thing inside the dash.

According to reviewers on Amazon, pairing to the BlackBerry is rarely needed. I am considering putting it in the ash/coin tray for quick access.

Here's some good info about making a hardwired USB power cable.
