I'm in the same boat as you. (tried to unpair the pro tel without sucsess)
But i only need the BMW pro telephone and a dual card.

 

But still, using your own mobile phone would be more convenient.
Dual SIM cards won't have the same numbers on them, you would save numbers on one and not the other.

The service manager told me that the kind of BT communication you have in your car is different, so I asked him to install the other BT adapter in my car so regular phones would work. He said that this option is not available yet.
Can you find out from you dealer if there is a possibility of installing it later on in the future?

 

what is option 6UA and can it be installed later ?

 

jmcaiado, how much are you paying for the retrofit?

 

I've payed 2050?. Meanwhyle BMW sent me a cheque worth 1300? as a refund.

 

What is the refund for?

 

To compensate for the money i spent with Business Nav in the first place (it was required with option 6UA) .
