I'm buying a new Ranger and don 't really feel I need the Sirius radio option. However, since I can't order and wait for one, I may be forced to take a vehicle with that option installed. It comes with a six month subscription. If I decide after six months that I don't want to renew, is the radio still completely functional as a AM/FM/MP3/CD player or will I have to continue my subscription to Sirius just to have anything. TIA
