Beware of Sony's warranty. A few months after I bought my Sony XM receiver, the fan started to make a very loud noise. I sent it back, under warranty, to have it repaired. They sent it back to me in the same condition, telling me there was nothing wrong with it, that it sounds just like the ones they bench-tested it against. I have to cover it with a box I lined with foam to muffle the noise, and I can still hear it. I will never by Sony again.
