Bought a used 100. I activated it but cannot get internet radio. I am signed up at Sirius for internet radio. I have 3 radios activated so I deactivated one and activated the Stiletto. It connects to the router fine but says to connect to a satellite channel to update sub. Due to the rain- I have not had this radio in the stream much- just to activate and update channels. Do I need to expose the radio to the stream more before WIFI will work?
