I have Sirius in my truck, direct connected, factory installed not frequency midulated(FM). It sounds much better than FM. They have a lot of excellent channels and as far as ads the only thing I hear is an occasional announcement of programming for different channels. I would get the Kenwood unit for your home it has an optical output so you could use a better processer if you have one. Let me know if you find a better deal than the $299 list as I'm thinking of getting it also.
