Cardongle was designed to improve user experience while driving a car. Due to that developers tried to keep things simple. Unfortunately some special tasks can't be done without having full access to Android.
This is just to inform you that there is a way to get into Android settings (not whilst driving, use it only for dealing with extended settings when the car is not moving!). Download from PlayStore "Open Settings" from DXldev. This allows to open the standard Android settings menu - might be essential to modify e.g. permissions or to add some Bluetooth dongles.
Bye for now Fred
