I just use a cell phone flexible charging cord plugged into the 12v outlet I mounted in the cubby box, leave some slack and close the lid with the cord exiting the top of the lid and attached to the input socket on the GPS. I only mount the GPS for trips so this method works well for me. If I were going to leave the GPS mounted on the handlebars, I would consider a more permanent wiring solution. Since 90% of the time I don't even have the bracket mounted on the handlebars, I have not found a need for running additional wiring.
