I bought the XM kit off of ebay Friday, suprisingly it was shipped Saturday and I got it Monday, today, Tuesday, I decided to tackle the installation and everything went really smooth. I took the rear seat off, the rear shelf off, the stop light and put the antenna inside the stop light, ran the wire under the shelf, under the rear curtain and unser the shelf again, behind the back of the rear seat to the side and ran it along the passenger side all the way to the front. I put the VAIS interface and the mini XM tuner under the glovebox and everything went really smooth. I called XM and turned it on. The only one thing I had to adjust was the sound level for the XM as it was was higher than the radio and CD so I programmed the XM sound level down to mach the rest of the components of the sound system. I was really surprised that although the antenna is inside the stop light and the previous owner added tinting to all windows including the rear at the dealer and getting the car inside the garage with the door closed and I still get reception.
