If by connectivity being Standard, mine says that...but I have full Satellite map and traffic visualizations displayed, so...must have Premium Connectivity anyway.
I am not sure where I would find "Immersive sound" as an option, but as I understand it, the SR+ does not have the extra speakers(connected) and sub-woofer required for it.
Do you have Fog Lights?
Yes,fog lights are a part of the partial premium. And they still work.
Immersive sound can be found within your audio settings. My option is no longer there. I did get satellite view recently, although I didn't not pay or get the email for premium connectivity. I'm in Canada FYI.
