I am wondering i currently have a temp subscription to this XM radio which i never even wanted but figured ill use it until it expires
is that where the navigation is getting its traffic info and updates ? or is it coming from my Lexus Enform subscription that i have ? like the part that says slow traffice 2 miles ahead on rout for instance do i have to worry about that going away if i stop a subscrition ? on my 2016 ES300h ?

 

For the 2013 and 2014 model years, the traffic information came from the XM signal and required and active subscription. For later model years, the traffic information has come from the HD radio signal, and it does not require any sort of paid subscription.
