Love the discover pro and I appreciate the bigger screen. Wireless CarPlay works very well and is so much better to the last 4 years I’ve spent with wires! It connects automatically.
There is an inbuilt SIM card I think, and that connects to the we connect system. There is also WiFi in the car but to be honest I’ve not figured it out yet. There is an option to buy a data plan, perhaps for this reason? I’m not sure I’d need that?
