My wife has an '04 X3 not pre-wired for satellite. She has nav and no cd changer. I bought the sirius kit with the wiring harness but I need install instructions. I had half the car taken apart last night but could not figure out where to plug into and run the wiring harness. I was under the impression that under the arm rest is where I had to connect and then run the harness to the back left side compartment. Does this sound right? Any and all help is greatly appreciated. If anyone has instructions that I could follow with step a to z including mounting the antenna in the rear spolier that would be great. TIA and Happy Holidays!!!
