It doesn't effect the function of your xm at all. If you plug your phone in the xm receiver will detect the audio and automatically shut off the xm audio. If you pause the audio without the channel being selected to 0 xm audio will resume on whatever channel it was you had selected..

Obviously this is only audio and it will not show artist name etc on the radio. :thumbup:
