I have sold all my XM gear, as I am selling the VW Jetta I had it installed in. But me and the wife are anxiously waiting to get it installed in the Xterra, because we miss it very much.
When you listen to the crap that is coming out in CD's these days (plus the $15.00 cost of a CD, more than one month of subscription to EITHER service), and then have to listen to constant babbling on commercial FM radio, you really miss the satellite if you've had it.
I will probably do an FM mod in the new truck. Main reason is I don't want to take out the factory unit and it's good, clean look. Don't get me wrong, the factory system in my XE sucks ass, but I still like the look of it..
