Hi. Am new here. I own a late 06' e90 320d. I boght a cic controller with the center console to do the upgrade. My old controller was the one with home button only.
I did everything to replace the old with the new cic controller but now the cic controller is not working at all. just the orange lights are coming up for a few seconds. What kind of software upgrade do i need? The bmw engineers told me that the car wont detect the new controller no matter what. Is that true? Please help.
