Just got hold of a swanky new hands free kit - a Parrot 3200 with colour screen. Tried to fit it, but I can't get any sound......
I have a Sony CDX-MP40 head unit. I have an amp powering front components connected to the front audio out terminals, an amp powering a sub connected to the rear audio out terminals (the head unit powers the rear speakers through the normal ISO connectors), and a Dension ICElink connected to the audio in terminals (a mikeythemini special

).
I have managed to get the kit to mute OK by connecting the HU's ATT lead to the mute feed from the Parrot kit. The Parrot kit connects to the HU via ISO connectors.
Does anyone have any idea why I'm getting no sound, and how to fix????
