I was driving one night when all of a sudden my radio, radio lights, and I drive screen shut off, I checked the fuse for the I drive, reset battery, hard reset on I drive and nothing, I went to the junk yard and found a ccc module exactly like the one I have now. (Not the module with 8 buttons) I installed and it didn't fix it my issue, screen is still black and no music. Do I need to code anything to get i drive or music to turn on? The car I pulled the ccc module off was dead with no battery so I can't verify if it worked but it was worth a shot.

There are multiple fuses I believe for the ccc system. Did you check them all ? Next step would be to check the unit is actually getting power at the cable that goes into the back of the unit with a multimeter. I’m trouble shooting a non functioning idrive controller wheel and buttons right now … hope you find your solution !

There is one at the back of the Unit in addition to the
ones in the Cabin Fuse board.
Checking the power with a volt meter is recommended.
