I thought the Iconic trim came with a 1 year subscription. Do you still have your window sticker?
Just a note that Sirius still doesn't think my May build Iconic radio qualifies for any free trial.... I will have to talk to the dealer again. I had been out enjoying the wonderful HK radio via Apple music, so I haven't bothered to check until today.
Despite the nice programming and full country coverage, I swore off SXM years ago. Their model of forcing you to sign up for an auto-renewal subscription and then "allowing" you to cancel (soooo painfully), as well as the pricing always jumping up to 3x the initial price, made me hate them. Especially as an owner with several cars, I used to spend many hours per year fighting with them, walking back automagic increases and renewals. It just felt gross, having a company deliberately making an overpriced, hard-to-cancel subscription the model. Now, Spotify is my jam.
The advantage to SiriusXM comes into focus when one finds oneself driving through such remote areas there isn't even cell service, like the desert southwest. So much better than the awful terrestrial radio often found in those same regions.
