Used cic coding 2011 M3
Car was purchased recently with no sound at all. Previous owner installed an incorrect cic part number, it was too old. I purchased a 07/10 cic for my 04/11. My car originally came with nav. Can someone walk me through coding this used cic to my vin and help get nav back as well? Most of the videos I see are for cic retrofits. I’m new to coding but have all the tools installed on my laptop.

Other than getting a dealer to restore the FSC, your options are: Hardware: Install an "emulator", basically a simple device that intercepts CANbus messages to and from the CIC. Find them on ebay search E90 CIC emulator Software: Search "CIC patcher", "FSTool2" or look at this link: https://cartechnology.co.uk/showthread.php?tid=23198. Frankly, this can be tricky and unless you are relatively computer savvy, you might want to pay someone to do it remotely. |

Look on the E90post forums - lots of people do remote coding, some of them will be able to do the patching and FSC write.
Bimmer-tech.net can do this - they're on the expensive side though |

Paid alpinemss for the remote coding. He was worried because he says when you install a used cic you should get some sound, I had none. After coding, sound works again. He said the firmware was old.
This was a tough one to diagnose because the previous owner messed with the car. I used ista to play test tones through the amp module and got the speakers to work when diagnosing. Bypassed the combox, still no sound. Traced the entire most loop, it was fine. After replacing the cic with a used unit and no coding I was getting no sound and 4 codes for speaker output leads open circuit. |
