For those with car pc, there is now XM radio for the pc

My Sirius satallie (car) subscription has always had Internet access. I can listen to Sat. on any pc I use, home or office or anywhere.
I have my audio card wired to my Surround Sound amp in the living room with speakers in every major room in the house and 4 speakers outside. I listen to Sat. music throughout my house.

 

Yeah, sirus has XM over the internet. But this is like the receiver for the PC, no internet connection needed (hence for the car pc)
