I'm not Kluken, but my husband did it on my car. He put the antenna (magnetic mount) on the roof above the front side passenger door side of the windshield, and ran the wire down the rain channel to the bottom of the windshield. He threaded it through the body to just above the hinge where the door and car meet, and somehow threaded it inside the car and behind the dashboard from there. I believe he said something about getting to it from the glove box, but I'm not exactly sure how he did it.

I guess there's some kind of punch-out on side of the center dashboard post on the passenger side - he punched that out to get to the antenna cable from inside the bottom door (the one with the aux jack) and threaded it though there, somehow. He then replaced the punch-out.

My Sirius receiver plugs in to everything (antenna, aux, power) behind that door at the bottom of the center dashboard. My reception is great.

I know I'm not the most helpful person in the world, but if I can get my husband to elaborate a little more, I'm sure his description will be much better.
