Is Sirius satellite radio actually available for the S40? I'm looking at purchasing a 2005 S40 T5 AWD, and I can't seem to find out if Sirius is available for it. I couldn't find any mention of it on the Volvo website, and the dealer didn't even know for sure, and suggested that I go with an aftermarket system. But I'd rather have an "invisible" factory-installed system.
