if your deck says it sat radio ready its a module thats like $200 but that module will ONLY stay in your car cause its wired into to it. Where was a portable sirius unit start at $70 and goes up to 250 for a top of the line stilletto. SO with the portable you can take it from your car into your home and play your radio there. Its 15/month but there are deals depednig on your contract. adn you can get a lifetime membership to!!! so unless you dont care about teh portability issue and the that the radio will display on your deck go get the module if not get teh portable sirius
