Hello There!!

I am trying to install a parrot LS3200 bluetooth hands free kit into my 2001 S3.

I have purchased the correct ISO adaptors to fit it but now installed its all working correctly however when the sterio mutes to make/recieve a call nothing can be heard through the speakers.

I have been advised by the sellor of the ISO adaptor that the sterio needs to be programmed for Phone??

Is this possible and if so anybody know how I can do this??

Thanks in advance
