Hi everyone,
I recently retrofitted NBT in my 2012 F30. I got a complete package wich was supposed to be ''plug and play'' but after installing everything i have no sound at all and the new touch controller is not working (kcan1 - kcan2 if i understand correctly.)

I have read that other people have had the same problem and there are a couple of options but i dont know what to try first.
The car came with HU_CHAMP 2 with nav (no combox) and the new NBT should be coded to my VIN by the seller.

Any help/advice would be greatly apreciated!
