It sounds like they aren't trying very hard. WHen I ran my Sirius, I put it in the center cubby above the center console area. I ran the power up from the accesory port that is to the left of the center ashtray. I'm still using the actual accessory "plug in", (I'm not sold on the sound quality of satelite radio yet). When I go permanet, I'll just tap into the two wires behind the panel. I ran the antenna from the back of the car. It is mounted to the right of that plug with two sided tape/antenna magnet. I popped the plug that is to the raer of the roof glass, it is held on with two-sided tape mostly, pulled all the old off and put new tape on and cut a notch for the antenna wire. The wire is run down into the hole under the plug, left across the back and then forward along the roof linedown the A-pillar and across to the receiver. The LR3 panels are almost two simple to remove. The console panel is held on with clips, the panel beneath the steering wheel has clips at the tops, pull toward the rear of the car, then fold down and remove. Run along the roof line by pulling the weather strips down alog the doors for access. Be cautious to use no pointy objects, and run the antenna wire to the OUTSIDE of the airbags. The panel @ the rear of the car, just pull on one corner and the clips should slowly let go. This is a guideline of what I did. There are numerous threads on Sirius installs that the search function will bring up, that have more detail on panel removal. I hope that this helps.
