Hello all - I am planning an install of the SharkFin antenna, with the "mini" Sirius antenna (that I already have) under it much like others have done with XM. My question is this... Does anyone have detailed instructions about how they routed the antenna cable once it was inside the headliner? I would like to go down one of the rear pillars and under the rear seat, then under the center console and up to behind the dash. Any help appreciated!
