So i purchased the idrive usb coding - mainly wanted the bluetooth audio - from BimmerTech (
https://www.bimmer-tech.net/bmw-idrive-coding/ ) and have been using it for a couple months now.
First off i have to say the customer services was great. I had issues installing the upgrade at first where the bluetooth audio would cut off a couple minutes after connecting and playing audio. I emailed customer service and they told me to update my idrive software to the latest version and even provided a link. After doing that and reinstalling the upgrade all was working perfectly. No issues with it so far and very happy with the purchase.
These guys are great and highly recommended to anyone wanting to upgrade their idrive with missing features.
