Your post was very helpful! I have had my 2019 Ram in the shop 5 times and no one could figure it out. Thank you! Easy fix!I figured it out! You have to have a user assigned to your SXM. To do that, go to settings, Sirius XM Setup, add a user. If there is no user listed it doesn’t know what to do and just defaults it all every time.
Yeehaww!
