E90 Idrive with nav
Recently my Idrive was rebooting a lot and so I did a 3 button reset. After this, it worked perfectly the next time. However the following morning my Idrive just stopped working. Not only that my CD dvd and information system all stopped working. To make things worse, the CCC fan was also running continuously so I had to quickly remove the CCC fuse.
1) is my CCC module dead? How can I verify?
2) can I replace my CCC with a CIC (from a e60) if I can get all the components?
3) when looking for a CCC, can I buy a used CCC when did not have nav or does the used unit need to have nav?
