I have no idea what's going on with my 2012 135i's CIC system. It won't recognize any USB format with the maps loaded onto it. I can see the USB key gets power so the port isn't dead. Strange enough the same USB key with the same maps and formatting work in my 2012 M3.
Any idea why my E82 isn't recognizing the USB key? I'm using NA Premium 2019 single USB method...
