Did any of you guys tried disabling the Telematics (contact Toyota mothership via 4G LTE link) on your Cross or any other recent model of Toyota?
I know you can contact the SOS support group and ask them to disable it for your car, but I do not trust them to disable it completely.
I found some interesting bits of information about the wiring for the Telephone/MAYDAY assembly:
TELEPHONE & MAYDAY. 2022 toyota Corolla Cross | Toyota , but I don't know if anyone tried and what sort of success they had with it.
Did any of you guys tried disconnecting the antenna or the transceiver cable? What was the effect?
