Mine came with a Sirius radio as part of Nav system; the antenna mounted inside the windshield behind rear view mirror; and a 6 months subscription as part of car purchase. Works fine with very occasional cutoffs of signal when going thru tunnels or heavily treed areas with tree limbs overhanging the street. Mine came from the factory with the option already installed. If I extend before 6 months is up, I can get a $9.95/mo pkg with a commitment to 1 yr or more.
