The SL may still have it. Does the 2017 MY Bose system still have the CD player? Anyone...? Given that they just limited the Premium Package to the SL and made it standard, it wouldn't make sense to delete the player, unless Bose wanted to do so, had already done so in 2016 or 2017, or offered Nissan a deal if they could do it in the 2018.
I can see it now: "The Latest Compact Disk Technology - available only in the SL!"

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.
