Bmw 325d 2011 with idrive cic and combox

The aux doesnt play music neither does the usb on a stick.(both in the armrest) The usb charges though.

The bluetooth just says please wait and doesnt change from that screen.

Have tried to update but the idrive says that there is no previous software version and it reads no usb in the armrest usb slot to update it.

I have formatted the usb and got the correct file on it. Ive reset the idrive by holding the mute for 30 secs. I have also checked the combox connections. The fuses have been quickly checked but i wasnt entirely sure which ones to check.

Someone please help... this is a minor issue but flicking between radio 1 and the 3 different heart stations is getting a bit tedious!

Combox , both usb aux and bluetooth come from there.

So does this mean a new combox or are they repairable?

Have you tried diagnostics.
I would see if you can run diags on the car an or if you
can talk to it.
If you tried to change the software on the head unit maybe
it was not included in the update.
I would go to the connected idrive sub forum to see if they have
any answers.

not repairable I would guess but software could be and issue to .
Did you check the combox fuse.

Be sure and include a history of how this came about or is
this car new to you?

do your car e93 ? cabrio ?
if yes, look for combox in trunk, pictures of the module you can find in google
they are often damaged by water leaked thru cabrio roof due rubber wear

I had this exact same issue, it was a break in the MOST loop. For me it was an antenna under the driver side footwell. As soon as I plugged it back in, it was like magic when everything started to work again. Normally there is a code for "break in the MOST loop" but for whatever reason it wasn't throwing it for me. I no longer have it, but try and find a diagram showing all the points of the loop and go through one by one to see if they're okay.

Appologies for not replying sooner ...

The car is e93 convertible hard top
I have run diagnostics and doesnt come up with anything
Its a new car to me bought from my cousin
I have looked at the combox and reconnected all connectors to make sure the were clipped in.

Will have a look at the MOST LOOP today

[ptpending]

have you tried to disconnect MOST, and 26-pin socket, connect only 26-pin socket and see if combox emit red light from it's MOST connector ?

[Newbie12345]

I have just checked. There is light coming from that connector. Well..for a brief few seconds if thats correct?

[ptpending]

the light coming from combox socket or green plug which connected to it ?

[Newbie12345]

Combox socket

[ptpending]

thats good, then look for other modules with MOST bus near, and check them using same method

[Newbie12345]

Found one behind the glove box but light is only coming out from one side/one fibre is this normal?

[ptpending]

yep, this connector should have MOST loop connected always except when diagnostic ICOM is connected
did it was connected firm ?

[Newbie12345]

Should there be something connected to this as it just seems to be a blank ?

[Newbie12345]

I am a bit of a newb on BMW should this be connected in the boot?

[ptpending]

this may be cd-changer preparation , it is usually not in MOST loop unless you have cd-changer in your options list

Hello Everyone!

I am having the exact same issue here with a 2012 BMW 328i E93 hardtop convertible with CIC/combox and am looking for a little more clarification on how to proceed. The local BMW dealer diagnosed the problem as a fault with the combox with a good fuse check. Because the fuse checked good, my next thought was to unplug the combox and let it sit for a while before plugging it back in and trying to reconnect to it via bluetooth. However, the combox is halfway under the rear seat/trunk panel. I have not been able to find a guide on how to remove the panel to get access to the other side of the combox to try and unplug it. I've tried putting the back seat down and taking out the rear right seat to get to it but both do not open the portion where the combox is located.

Looking for any advice on how to unplug the combox or reset it via NCS expert as mentioned here.

Thanks!

First picture might give you a hint.

You use to be able to get install and removal procedures on the
tis now you have to have Ista D or Ista + to get the same stuff.

The combox itself was bad, replaced it and plugged in the new one and it worked no problem with no coding.

Hi I am in the same boat currently, did you buy a new one or used? I am ordering a used one and wonder if a used one needs to be recoded.
