Audi a4 b7 telephone instillation

Hi, new to this forum, this is the first time i've posted. I have a 57 plate audi a4, with rns-e satnav. I recently decided to install the original audi bluetooth telephone module. Got the unit and the wiring installed, but it still says telephone not installed on the satnav unit. My phone can see the bluetooth but wont connect (is this because i am inputting the wrong pairing code or because its not installed?).

I presume its because the coding needs to be changed to install the module. Does anyone know either what the code is, where i can find the correct code or which digits need to be changed? I'm using OBDeleven and i'll attach a pic with the current code

Thanks
