UPDATING: The encryption code in the receiver is being updated, and no action is required. This process should take no longer than 30 seconds.
NO SIGNAL: The system is functioning correctly, but the vehicle is in a location that is blocking the SiriusXM signal. When the vehicle is moved into an open area, the signal should return.
LOADING: The audio system is acquiring and processing audio and text data. No action is needed. This message should disappear shortly. OFF AIR: This channel is not currently in service. Tune in to another channel.
CH UNAVAILABLE: This previously assigned channel is no longer assigned. Tune to another station. If this station was one of the presets, choose another station for that preset button.
RADIO ID: If tuned to channel 0, this message alternates with the SiriusXM Radio eight-digit radio ID label. This label is needed to activate the service.
CHECK XM TUNER: If this message does not clear within a short period of time, the receiver could have a fault. Consult with your dealer.
