Before I start trawling the internet I wonder if any of you have experienced and sloved this problem? A colleague of mine has a B7 A4 and has a IPaq 6300 which he used as a PDA and a phone. When he got the PDA he linked it to the Audi Bluetooth phone prep and they all talked together nicely. He recently installed Tom Tom 5 on the PDA with a wire GPS receiver, this too works fine. Problem is, now, when you have the bluetooth turned on the voice on the TT no longer works. Tha application runs fine and it works through the maps and directions but no voice. Turn the bluettoth off and the voice comes back! Any ideas? Kev.
