i stuck mine on the roof, a few inches back from the windshield. i used the tape that came with the radio. the wire runs forward to the front edge of the roof, under a plastic cover that also came with the kit. the wire then goes to the drivers side, along the top of the windshield. i used some black electrical tape to keep it in the groove at the top of the windshield. then the wire is tucked under the side trim and drops behind the left fender. then it goes across the drivers door seal and under the dash. no pinching. then to the radio hung under the stereo, using the sun visor mount, which is double-back-taped to the underside of the stereo console. power, antenna, and audio cables run to the sirius inside a black plastic tube to cut down on the visual clutter.
the mounting of the sirius may change soon. i am thinking of making a bracket to hold the sirius, an mp3 player, and a scangauge.
