I'm still trying to figure out my 2020 HSE. I enabled wifi in my car which works great and it allowed me to update my infotainment to 21B. My web browser will not work but once the dealer (claimed he can't push updates) updates my tcu to 19.2 I think web browsing will work. I have zero cell service at the house. I really didn't want to pay for the att hotspot. I guess the first question is should the browser work with wifi? How many of you have the ATT in-control service and is it worth it?
