I tried to program the Idrive system to accept Aux by myself, I used NCSExpert. It went well until the last piece of the download it said there was a communication error and that was it. The Idrive worked well for the first two weeks and even played the AUX but Now it turns off randomly. I did create a save file before I tried anything I am just not sure what to do at this point. Any help would be appreciated and If anyone In the NYC area could help out I would really be thankful.

 

I would suggest restoring the module to the original settings.

Did you change the vehicle order? If not, do that, then program the module (CCC or MASK) with the new settings.
