SXM Data/Infotainment encompasses ...
1) SXM Traffic (car/road not air

)
2) SXM Travel Link (weather, fuel prices, movie listings, sports scores and stocks)
Based on my current information the issue is with SXM Travel Link.
My 2018 G80 3.3T Sport (9.2"HD screen) was affected by this issue starting late January 2021.
Feb 19, 2021 my complimentary SXM Traffic AND Travel Link subscription expired. After subscription change was pushed to my car that day the issue went away.
Oddly, a SXM subscription update was pushed to my car Feb 26, 2021 (notified on car screen) adding SXM Traffic back in. I suspect Genesis/Hyundai or MapnSoft requested SXM make this change. SXM radio continued to function correctly after this subscription updated.
As of now ...
SXM Traffic is shown SUBscribed in car. Not shown in my SXM account online.
SXM Travel Link is shown UNsubscribed in car. Not shown in my SXM account online.
