Hello,

I'm about to retrofit everything to get the basic bluetooth option on my 2011 F25 (6NH option).
It's kinda weird as it has tons of options (including business nav), but it has no BT option. I guess the first owner thought it would automatically come with the nav system. Anyway...

I gonna have to retrofit the microphone and even cut the headliner to fit it but it looks kinda straight forward.

My main concern is that I don't know yet if I have microphone cable as std or not. If I don't, I have found an aftermarket cable which seems perfectly fine (https://www.ebay.fr/itm/BMW-CIC-NBT-...-/263898426679).
I gonna have to wire it on the big connector at the back of the CIC.

Can someone tell me which pins are the right ones?


(I haven't found any information on basic BT retrofit...)
