Hi, I have a 2015 S3 Technik (Canadian spec, no sim slot) and by using various sources from Forums and OBD11, I manage to make the "Audi Connect Menu" available on my MMI and also "Google Earth/STD map" in my NAV.

But, when I'm going into my "telephone>settings>Data Connection" the "data connection settings" is greyed out, does anyone know why ? How to make it available ?

What I've done so far:
--------------------------------------------------------------
Long coding
Control unit: 5F Information Control Unit
Values:
byte_15_Phone_NAD: (bit 4)
Old value: Off
New value: On
---------------------------------------------------------------
Adaptations 5F

Does anyone have an idea?
Thanks

Sorry forget to mention that I'm trying to use my smartphone as hotspot and the car as Wifi Client.
