Ok, so here goes..... I have a 2007 e92 325i (UK)
Bit of background, I had a the CIC retrofitted by someone in December, I have CIC fully up to date with 6nr already loaded....then I decided I could do the combox retrofit myself!
I bought a telematics combox because I found them more readily available on eBay, I do have the wiring for assist but eventually I will code all that out because I don't particularly want it even if I could get it working.
I have since fitted this but the problem I have run into is not being able to get the microphone for bluetooth telephone calls (I can hear people perfectly fine they just can't hear me) or the voice activation to hear me.
I have tried everything that I have read across all the forums and countless posts regarding trying to get this mic to work and I have come up empty handed. I have tried changing mic over most to aktiv and then nicht aktiv, I have checked my wiring over and over again. Finally located the mic wiring in the footwell and because it's a UK model it's in the drivers footwell and all that seems fine and doesn't seem to need repinning.
So....I bought another telematics combox, just in case the one I had was faulty, plugged it in on Wednesday just gone and coded it this morning but to no avail. I still have no working mic!
I feel like I can't move forward with anything else until I get this issue sorted, it's driving me nuts and is an important part of the car for me. I still have 6fl, 6nr, 6ns and 6nf to get my head around!
Previous to the combox retrofit I had just the TCU and previous to the CIC retrofit I had CCC and the bluetooth for calls worked really well, couldn't ever get voice activation to work, but once CIC was retrofitted the nice man who did it for me activated Voice activation too.
So up until me fitting the combox I had working bluetooth calls and working voice activation. I have tried swapping back to the TCU and it works just fine again so I know its not a coincidence and the mic packed up in between tcu removal and combox fitting.
Please can anyone help me with this? I just don't know what else to try/do.
Thank you for any help you can provide me.
