I have SiriusXM in my 2012 Chevy Volt, and in my 2018 Honda. I have the same subscription level for both vehicles, but I am not getting the same channels in both. I contacted SiriusXM and they told me to update the software, and gave me the instructions on doing it, which were a bit bizarre, like bringing up my account on my iPhone and taking it out to the car. The kicker though, is that I have to be tuned to channel 0, and the Volt does not have a channel 0. Anyone have any suggestions?
