Both SR and SR+ have:
"Standard maps & navigation"
To get "Live Traffic", you need Mid Range and higher.
I suppose there's a hacker who can figure all this out but would that person come out the closet is another matter.
Real time traffic is still a thing with the SR+. In fact, when I lose cell signal and deviate from the guided route, it will tell me when I’m no longer receiving traffic data. The only thing missing in the SR+ is the red/yellow/green colors on the map. There is also a toggle in the navigation menu to receive traffic data even though it won’t show it in colors.
