How do I set up and activate SiriusXM satellite radio service?

Press SRC/OFF to select [SIRIUSXM], then press the navigation buttons to select Channel 0 to display your Radio ID. Activate the service online at www.siriusxm.com/activatenow or by calling 1-866-635-2349 for US subscriptions, and [SUBSCRIPTION UPDATED] will appear on the display when successfully subscribed. The activation process usually takes 10 to 15 minutes but may take up to an hour — do not turn off the unit until the activation message is cleared. (Page 20-21)
