I have a 2014 Prius c and I just ordered a Sirius Onyx satellite radio since my radio is not sat equiped or "ready". Is there a way to hardwire it to my existing radio so I don't have to use my one and only 12v outlet and my one and only "aux. input" jack? If not, that's ok, but is there any danger in getting an expansion 12v add-on? I've seen them in auto parts stores where it converts one 12v outlet to two or three. Finally, anyone have any ideas as to sat radio placement and how to run the wires (power, aux in, and antenna) without it looking like a mess?
