Available on all trim levels as long as you have Sirius XM
Edit: appears not to be available on S trim level. Did not see it listed on window sticker, but did see it listed on SV and SL of 2018 model year window sticker.
You might be lucky because the app is flaky.
I have appt today at dealer service dept because Nissan Tech support says that the TCU is not communicating back to computer
