Side issue. You can save $$ by going to SiriusXM website and checking out their various packages. The little info from the car dealers and any renewal minders never discuss lesser costing programming. I switched from the full package to the "Mostly Music" package. IIRC, went from $16/mo to $10/mo and got rid of all the sports, comedy, news, and political garbage. I could have went less, but I wanted my 60's on 6, 70's on 7, etc. & that was the lowest package for that. I will have to investigate the ala cart deal. I only routinely listen to maybe 10 channels.
First trip with new camper, had no cell service at the site. So no radio via cell available.
