Hidden green engineering menu

[GlynH]

Hi there,

I have recently discovered the 'joys' of activating the hidden green engineering menu but was wondering if there was a resource anywhere that might list/detail what the multitude of menu entries/options might actually do?

I have enabled diagnose/settings/tel_settings/NAD operation mode” (default is for “NAD activation” to be enabled but “NAD operation mode” being disabled.)

This gives me the option to choose whether telephone calls go via the SIM in the car or via mobile over bluetooth.

Does anyone know what NAD stands for and more importantly what else/other settings can be changed?

Thanks & kind regards,
