I did a bluetooth install on 2004 B6 with RNS-E with Bose.The bluetooth module is 8P1862335A. I used the plag and play cable like this one: http://www.ebay.de/itm/Kabelsatz-Ha...9719?pt=Freisprechanlagen&hash=item19d34e3287 I coded the RNS-E 0309711 My phone pairs, dials etc and people can hear me when I call but I get no sound from my bluetooth unit. I get no pairing beep, no caller sound, but it does connect and show call time. It mutes the radio but no sound after. I have installed another radio unit (BNS 5.0) at the car and get the same problem. I have tried two plug and play bluetooth cables and get the same problem. I tried to install the bluetooth on another 2004 B6 with RNS-E but without Bose and I get sound and everything is ok. I have checked the C12 and C6 connections and everything is ok. Please help, this is driving me nuts!
