OK, I'm this close || to buying a 2007 Grand Touring. It's nicely loaded (Nav and the such), but for some idiotic reason, the dealer who ordered it didn't order satellite radio. It's the Stanley Cup playoffs (and my Kings haven't sniffed that in years), so I need my XM. I can't get a straight answer. I believe the BOSE system is prewired for satellite, and a dealer can install the XM. But the dealer says that no, the XM can only be ordered from the factory or I put in an aftermarket version (which I'm reluctant to do, just because of the beauty of the interior of the car). So, what's the truth?
