I purchased a new BT antenna that plugged into the back of the NBT unit

There is a pic on my DIY NBT retrofit thread in the DIY section of the forum

Is it because in cic and ccc the mic is plugged into the combox/mulf and for NBT it goes to the headunit ?

I have the instruction manual now from the europe guy we bought off. He also gave me map update for australia 2019 and the code plus the media centre update links aswell.

That's exactly right, the mic is plugged into the Bluetooth unit on the CIC/CCC and on nbt it's directly plugged in. We elected to run an extension from the boot to the headunit to reuse the factory mics

Hey I got this sent from the guys in Romania

Microphone must be wired to NBT according to the manual on pins 17 (+) and 22 (-), you need to check that pins from microphone are correctly wired and fully inserted in connector. Also you need to make sure that old BT module in the car was disconnected and removed and MOST bus (fiber optic) closed.

So does that mean to remove the module in the boot completely out? Im guessing it is rendered obsolete? Is this correct? Does our system not need anything further from the bluetooth unit??

MOST bus (fiber optic) closed. What and how do you do that?

[Aus335iguy]

There's a MOSt loop connector that you can buy to close the loop. Disconnect the other connector and you should be ok.

Bluetooth unit goes into the trash. NBT handles bluetooth. You could in theory just leave it connected in the boot and not cause any issues.

If you remove the bluetooth unit theres an optical fibre network in the car that it is a part of. Removing a module will break the optical fibre loop. You basically need to buy a blanking plug that has an optical fibre loop in it to pass the signal though.

So I removed the bluetooth module and noticed that the fiber optics connector has no red flashing light going to it. Ages ago when I put my meth tank in the installer removed what I believe was some nav com box or something on the left handside what I can remember and then ever since then had the SOS error. I just pulled apart the boot and noticed that the connector to that combox with the fiber isn't in the connector but has been looped somehow.

Anyway if I want to use the mics in the car do I run a line from the big connector that came off the bluetooth module which Im guessing certain wires are for the mic's. Is that correct how you did it on phils car?
