Hi, I purchased a Kenwood 893s stereo with SiriusXM ready; however, the dealer did not inform me that I cannot just contact SiriusXM, subscribe, and start listening (I take full blame for assuming and not asking questions - I am too upset to contact the car stereo dealer so now I am asking you, for help; what do I need to do to get my stereo in a position to subscribe to SiriusXM? Do I need some sort of an adaptor? I have CarPlay but cannot find out how to find my radio ID?
