[M135imike]

Hey people!

Recently fitted nbt to my f20 m135i which had business nav, Bluetooth etc , I think it may be CIC? Possibly wrong

But I’m having issues with my USB port and the sound.

The USB port in the armrest charges my phone, but doesn’t show in the multimedia menu on the screen etc.

And the sound only works if I have my engine running, not while ignition only is on?

Anyone that can shed some light on these issues and a resolution would be great!!
