The owners manual says that for the 12 inch screen "SiriusXM Setup — If Equipped After pressing the “SiriusXM Setup” button on the touchscreen, the following settings will be available: ".........."SiriusXM can be programmed to designate a group of channels that are the most desirable to listen to or to SiriusXM can be programmed to designate a group of channels that are the most desirable to listen to or to exclude undesirable channels while scanning.. This feature allows you to select the channels you would like to skip.". Problem is that I don't see this option.
