XM is included only in the Entune systems with Nav on the Rav.
If you just have the basic Entune, you don't have it.
There are technically 4 levels of Entune, but it seems that Toyota doesn't offer the 2nd level, which is Entune Audio Plus which is the basic system plus XM/HD.
They jump from the basic "featureless" unit to the Premium with app suite and navigation.
Sad, because the Audio-Plus is really all I want.
I don't care for the Nav system, generally use Waze for the most part. Not having an unlimited data plan, Pandora, Slacker, and iHeart are 100% worthless to me.
