I just bought a 2006 S Murano last weekend, and so far I really love this vehicle. Since I have the base model, still well equipped in my opinion, this may be the answer to my question. I noticed a huge difference in the sound quality between listening to a CD versus FM. In other cars I've owned I've never experienced quite this much of a difference. I am concerend a bit because I have an XM SkyFi 2 I am going to install this weekend and sure would hate to lose that sound quality. Any ideas? Thanks!
