Parts for combox install. Have I got everything covered?

I've found a combox on ebay that would be suitable for my car and just need some clarification as to whether I have got all the parts for fitting correct.

My car is an 09/06 build e92 335d. I have fitted the Cic already and its been working great for a while now. Its combox ready. I have only the TCU module fitted for bluetooth/phone prep and Bmw assist. I have never used bmw assist and have no need for it so coding this out would be no problem. The only other thing is a standard aux only input under the armrest.

Through some research, I figure I need these parts:-

Combox from ebay

61136913644 - 26 pin connector for tcu to combox plug

61136913626 - 26 pin connector housing for tcu to combox plug

84109237653 - Usb/Aux socket for arm rest. (4pin) Although seems to be discontinued, my local dealer says they have some.

61119129360 - Usb Hsd cable to connect usb socket to combox

61129187009 - Usb/aux harness. (I'm not sure if this is needed or not)

Coding to car


Could anyone please advise if I have everything coverd for a straight forward install or if I'm missing something. Any info would be appreciated.

Thank you all

You don't need that one.

You will need to run 4 new wires from the aux/usb plug to the 26pin connector for aux to function properly. So you may want to order 4 females pins to insert into the combox socket and some wire to run to the aux socket.

Thank you very much for your response. Once the 4 new pins are run to the 26pin combox connector for aux, will the current aux connector going to h/u be redundant?

Also Ive attatched an image of the current coax side of my tcu unit.

I believe the one to the far right (white/purple) is the bluetooth antenna that connects to the combox. The other 2 on the left I have no idea about. Are these to do with bmw assist, so when coded out will they become redundant?

Thank you for your help

They won't be used unless you have a Combox Telematics. If you have a Combox Media, they'll just sit unconnected.

Thanks for your reply's guys. There is one more thing I'm unsure about. Does the manufacturing date of the combox matter? I have seen a combox with 2011 date and one with 2014 build date. Of course I'm thinking I would rather have the younger one. My Cic was from 2011 car. Will I have problems?

Thanks you

As long as it says BN2000 you should be good to go. The wires leading to the head unit for aux just leave unplugged.

Got my combox through and upon re pining to the 26pin connector, I've noticed there are 2 wires not accounted for. Pin 3 Blue wire and Pin 46 Green wire.
I think pin 3 is for snap in but does anyone know what pin 46 green wire is for?

Thanks
