Lost power to the Idrive controller

Im not sure where this post should go but I lost power to my idrive controller. I'm not sure if anyone else has had this happen. Any tips would be appreciated.

I was told that is has a constant power source and that it should have power when my lights are on, but I'm not getting any power to it at all. I just had the Alpine B3 transmission programing done to the car if that helps with anything. I dont think that could cause it to lose power and I haven't done anything else to the car. It is a 2011 335i Xdrive coupe.



Thanks
