Well ill help ya out if i can...I had XM in my 95 coupe and it was very nice. I liked it and cancelled it because i got real tight on money and had to sell the radio and controller..But i had my antenna on my trunk...It comes with a magnetic base and its fairly easy to run the antenna wire to the trunk...But if you dont know your way around radios and car stereo...Have to tap into your factory atntenna...gotta tap into power...just time consuming really.
