Hello,after looking as much as I could through the forums here and not finding the answer im posting this. I just became a new owner of a 2015 Altima 2.5SL and had one issue with it. I do not have a subscription the Sirius xm radio, and do not wish to do so either. This wouldn't matter to me at all if when i press the source button I could skip over the Sirius channels, but after reading through different stuff online I cannot do so because of their channel 1 promo channel or what ever. Is there a way i can disable the Sirius xm radio from the source button, and also is there a way where the source button will only cycle through media that is connected to the vehicle, because even though I haven't connected anything via AUX or bluetooth it still cycles through those when I'm pressing the source button.
