How does the data leave the device? I tried to route traffic from the infotainment system into a WiFi network I was wiresharking, and I saw a lot of GM traffic but I couldn’t install a cert to MitM because I couldn’t figure out how to access the Android settings for the dash OS.

Is the traffic through there or is it totally within the CANBUS and never hits the WiFi outbound? In that case do you need to hijack the 4G?
