Bluetooth Retrofit Help

hernandez706 · 09-19-2014, 07:13 PM

Hey guys, I have a 2011 135i which came with the combox, but no Bluetooth. I was told the retrofit would be fairly easy on my model since the most complicated part was already installed. I thought buying the microphone and getting the proper coding done would get it to work. However, it turns out I don't have the cable that connects the mic to the combox "preinstalled". I'm pretty sure the E90s have this cable already sitting there. I tried to locate this cable, but have been unable to. Can anyone help? Thanks!

I doubt that you have it, but to be sure, check the connections on the combox. I don't have the pinout diagram in my head, but you'll find it by Googling a bit. Check where the microphone wires should be, and then check if there are any wires on that location. If not, then you'll have to install them yourself. It's not that hard.
