I'll add to this for those who may be interested.....
Through 06/30/21, SiriusXM has their "Big Summer Upgrade" sale. It's 12 months of Select for 4.99, which is then upgraded to All-Access at no charge. Once those 12 months have passes, reverts to just Select at the 16.99/mo rate, (ie; time to call/webchat with them).
$5/mo for All-Access for a year is one of the best deals. Last I checked, $60 < $99, so I'm sold!
(This actually timed out great, as we still have one month of our free trial in the new Acura, so signed up online yesterday, and will get charged on 08/01/21 for $6.36 after the royalty fee and taxes)
Edit - All I saw online was the 'standard special' for 12mo for $60 on the Select, which didn't include the upgrade. I had to google "siriusxm select upgrade howard stern" and a few links down was the correct one to get the free upgrade for All-Access.
