Aux. power outlet

I need more electrical power for my electronic helpers. I currently power my Precedus GPS(mounted on a RAM suction cup mount), a TPAS collision avoidance device, and my Anywheremap/AI. Does anyone know of a method to use the ANR power connectors for extra electrical power? I am considering the Anywheremap weather (impatient with Anidyne) and would appreciate any feedback.
