Here's how I installed my XM Sky-Fi a few years ago.
I ran the XM antenna right out through the hole in the roof where the stock antenna is located to hide the wire. I then ran the wire under the rear vent on the back of the roof and down along the passenger side of the VX behind the interior panels towards the front. I took a sharp turn right behind the front passenger seat and slid the cable under the carpet a few inches (where the front and rear carpets meet). I mounted the FM modulator behind the glove box in the dash. I hooked the XM antenna wire to the stock radio antenna wire at the back of the radio (about a foot from the back where the antenna wire connects to the radio). I mounted the Sky-Fi unit in the center console right next to the e-brake and drilled a small whole in the platic to tuck all the wires in directly beneath it. No wires can be seen AT ALL with this installation which is the way I like it![]()
Operating the Sky-Fi unit from this location is very easy as it sits right below your hand while your arm rests on the center console. If you're not familiar with the Sky-Fi unit, this can be a distracting place for it but once you know were all the buttons are it's very easy to use. You could always use the remote control too for less distraction.
I do like the idea of having it tucked into the spoiler like Joe_Black has done here but would question it's reception in some areas for the XM folks. Sirrius seems to have better reception then XM when it comes to trees (with wet leaves on them) or thickly settled areas such as cities or Mt. Sides.
If you have any questions, just ask![]()
