I have everything you need to do your own conversion to factory 6NR.
I have the following:
Base plate for 6NF: 84109239396 - Used removed from 2011 E90 with 6NR
Trim: 51167118054- Used removed from 2011 E90 with 6NR
OEM BMW Apple iPhone 4/4S Media / BMW APPS Version Snap In Adapter: 84212218390 - Sold
PN XXXX - BMW USB cable to connect Module in the trunk to the Base Plate - New
Custom FSB cable to connect the Base Plate to the headunit.
All you need to do is re-code your car with 6NR option. There are few members on the forum that can do it remotely.
Asking price: $300
