CIC Firmware Upgrade on BMW E90

Hi all bimmers =)
I would like to update my CIC since I never did, I just updated the software that you download at BMW.com/update. Do we have anyone here on the forum who has updated their CIC?

Not sure if you are asking who has installed the "update" from BMW.com or who has updated the program code on their CIC, which are two very different things. I've done both.

The BMW.com "update" just makes a few subtle changes. If you've looked at the PDF description on BMW.com, this "update" came out at about the time that iPhone iOS5 came out. Not exactly current. To update the program code, you need BMW standard tools installed on your laptop (to obtain the flashing program WinKFP) and most would say you need an ICOM interface. In fact, I've done the flash with a Bimmergeeks K/DCAN cable but be warned you can cause unrecoverable damage if you don't do things correctly.

In the end, there is nothing in this world that will make the CIC as functional as what's installed in a 2019 base model Nissan Versa. It's just too old. The real update would be to retrofit an NBT Evo headunit but that's a very complex and expensive job.
