I found plenty of online resources for combox retrofit but did not really get the basics of it while it comes to buying the actual unit.
My 2011 335i has the Bluetooth phone, navigation professional but no Bluetooth audio. It has the continental TCU.
I am planning to retrofit the combox from later models for the Bluetooth audio. I found lot of such items in eBay for as low as $75. What I need to know is which one to order. Will any of the combox work ? I know it involves coding but I am looking for the actual hardware part.
As an example-84109257163 is the part number I got from many eBay searches.
Thanks in advance.

Bump, not sure but I wonder if there is the same thing for my 2006 330i logic 7 set up. I use a dongle on the plug in the console however it is awkward at best.

I have found this post is the most comprehensive guide-

I have ordered the connectors and the combox as mentioned in the post.
What I have figured out - if you have Exx series, you need combox-BN2000. Search in Ebay ane you will get many of them. BN2010 supposedly is for F series.
