2018 SL does not have WiFi connectivity capability. Wanting to know has anyone managed to update software or change out factory radio to newer model to fix this?

Disclaimer: I am aware there are third party options to have WiFi in vehicle via different adapters and plug in options. However, I would really like to limit the number of external adapters and wires.

I’m looking to find a way to update the current system or to learn if any one has successfully changed the radio system from 2018 SL version w/o WiFi capability, to newer model/more upgraded model with WiFi?
