I really prefer Sirius. The rock programming at least is so much more my taste. Also, I love the DJ's on Sirius. The one's on XM are just annoying.
Anyway, love the Murano. It's fun to drive. Love the AWD. Can't spin the tires, even in the rain. Suspension is awesome. Feel like it's unstoppable. Music options are fantastic. I use them all, except the Flash (kinda of overkill, as I prefer the iPod, but nice to have as an option.) I get lots of compliments on it. If I can remember while it's light outside, I'll post some pics. I put 20" Incubus (
