Someone reported in a Dutch Forum (Tweakers.net) that the MG ZS EVs in the Netherlands are equipped with the following XBOX module. Apparently this is used in SOS situations so emergency services are automatically informed and dispatched.
It might well be that this xbox can also be used for car telemetry and possibly for the AP and Wireless features as pointed out in the head unit software.
I do see that I have an hidden wifi network. So I will try to connect with credentials provided earlier and with the SAIC Link app for iOS.
